3x+2 / 2 =7?

Question

3x+2 / 2 =7?

Answer 1

The answer is 4.

because 3 times 4 is 12

...add 2 u get 14

14 divided 2 is 7

get it...hope this helps...= P

Answer 2

if your looking for the variable x, it could be 2 or 4

2 because:

3x+1=7

     -1  -1

3x=6

3x/3=6/3

x=2

or

4 because:

(3x+2)/2=7

3x+2=14

     -2   -2

3x/3=12/3

x=4

hope that helps....

Answer 3

x = 2.

Sorry but there are *not* 2 correct answers to this expression.

Without altering the expression by inserting brackets (when none exist in the original), x does not - and can not - equal 4.

It isn't difficult. I've no idea how old you are but I'd say this 'problem' belongs in primary maths.

Whilst I can see how some people might come up with x=4, in order to get x=4, it would have to be written as (3x + 2) / 2 =  7...which it clearly isn't!  

Remember BIDMAS and notice that there are no brackets in this expression.

Anyway if you cheat/check and put 3x+2/2=7 into a calculator, it will tell you x=2.

If x = 4, the expression would have to be 3x + 2/2 = 13

Those people who believe x=4 are effectively doing:

(3x + 2 )/ 2 = 7 -->

(3 x 4 +2)/ 2 = 7 -->

14/2 = 7 -->

7=7

which is correct, but is not what the expression is actually asking you for!!.

What this (wholly unbracketed!) expression is actually asking you to do is:

3x + 2/2 = 7 -->

3 x 2 + 2/2 = 7 -->

3 x 2 + 1 = 7 -->

6 + 1 = 7 -->

7 = 7

If x=4, it becomes 3 x 4 + 2/2 --> 3x4+1 -->13

Or in other words:

those who reckon x=4 are inadvertently doing

3 x 4 + 2                                                        

------------   =  7    

     2

BUT

what the expression is actually asking for is:  3 x 2 +

2

           --- = 7

            2

x = 2.

Or another, 'nother way:

3x + 2/2 = 7 (remember: no brackets!)

3x + 1 = 7 (now can you see why x=2!)

3x = 7 - 1

3x = 6

x = 6/3

x = 2.

Answer 4

3x + 2/2 = 7

2/2=1

3x + 1 = 7

      -1    -1

3x + 0 = 6

3x = 6

6/3= 2

x = 2?

I don't know: I suck at math!!!

Answer 5

x = 4  : 3 times 4 is 12 plus 2 is 14 divided by 2 is 7

Answer 6

Firstly, we must do reverse PEMDAS.

Just by looking at th problem, I see 2/2 can be simplified and made into the number 1.  Therefore, the problem now becomes: 3x+1=7

Subtract 1 from both sides and you are left with:3x=6

Divide 3 on both sides and x=2.

Hope this helps!

P.S. THE ANSWER CANNOT BE 4 IF YOU FOLLOW PEMDAS!

Answer 7

x=2

2/2=1

7-1=6

6/3=2

x=2

Answer 8

see this is why math is a F***ED up useless pile of S***! 2 answers for the same question? bah humbug!

flunk it. i did since grade 8...i got A's - A+'s on everythign else though. but math i just gave up on it since grade 8 onward. i dont need math for what i do anyway (horse riding...) what...im gonna multyply the hairs in Dixie's mane & tail? lol

anyhow...im 26 now & get a long just fine in life with out math. true the rest of school was A's but still...ya dont need it.

Answer 9

3x+2/2=7

3x+1=7

     -1 -1

3x=6

/3   /3

X=2

Answer 10

4

Answer 11

it's either 2 or 4

Answer 12

3x+2/2=7

(multiply both sides by two to get rid of the denominator - 2)

3x+2 = 14

(subtract 2 from both sides)

3x = 12

(divide both sides by 3)

x=4

(you're dividing everything on that one side by 2 right?

if no, then here's another answer)

3x+2/2=7

(simplify the fraction 2/2 which equals 1)

3x+1=7

(subtract 1 from both sides)

3x=6

(divide both sides by 3)

x=2

Answer 13

3x+1=7

3x=7-1

3x=6

x=6\3

x=2

Answer 14

x=4

as 7*2=14

14-2=12

12/3=4

Answer 15

x=2. first take 2/2 and that is 1. subtract 1from each side and u have 3x=6. divide each side by 3 and u r left with x=2

Answer 16

3x+2/2 = 7. First, multiply 2 to both sides and you get 3x+2=14. Then, just solve using backward PEMDAS. The answer is 4.

Answer 17

x= 4

Answer 18

3?

3x+2 divided by 2 equals 14 divided by 2 =

cross multiply =

6x + 4 = 28

x = 3

Answer 19

x=4

when you do the order of operations you multiple 3 and 4 and get 12 and then add 2 which equals 14 and then divide 14 by 2 which equals 7.   I hope I helped.   Good Luck!:)
