Question

I found that 6 is the answer of -5(x+2) +3=5. How do you check and see if its right?

Answer 1

just plug 6 in for X

Answer 2

-5(x + 2) + 3 = 5

-5(6 + 2) + 3 = 5

-5(8) + 3 = 5

-40 + 3 = 5

-37 = 5

oops, looks like 6 is an incorrect answer.

Now to solve for the correct value of x

-5(x + 2) + 3 = 5

-5x - 10 + 3 = 5

-5x - 7 = 5

-5x = 5 + 7

-5x = 12

x = 12/(-5)

x = -12/5

Answer 3

-5(x+2) + 3= 5

-5x -10 +3 = 5

-5x = 5 +10-3

-5x= 12

5x= -12

x = -12/5

I think your answer is wrong...this is what I got not sure if its right

if you plug 6 into the equation it doesn't work out so i guess you should try again!

Answer 4

put six in for x and see if both sides end up equal.

Answer 5

I use the method PWAC. Problem,Work,Answer,Check.

(it sounds like Quack with a P)

Problem: -5(x+2)+3=5

Work:(plug 6 in) -5(6+2)+3=5

                        -5(8)+3=5

                         -40+3=5

Answer:              -37=5   X

And to check... you get the idea.

but apparnently 6 is not the answer.

Answer 6

-5(6+2)+3=5

-5(8)+3=5

-40+3=5

-37=5 FALSE

Answer 7

plug it in

since X=6

So replace 6 w/ X

-5(6+2) +3=5

-30 + -10 +3 =5

40+3 =5

43 = 5

43/5 =

X=8.6

so you need to recheck your answer

Answer 8

first of all in -5(X+2) + 3=5     X doesnt equal 6 it equals -12/5...

subtract 3 to the right side to get -5(X+2)=2

then distribute to make it -5X + -10=2

add 10 to the right side to make it -5X=12

divide the right side by -5 to make it X= -12/5

then to see if it is right plug -12/5 back into the original equation for X.

Answer 9

you would substitute 6 for x

Answer 10

6 is not the right answer -5(6+2)+3=-37 not 5 x is lower then 6  

Answer 11

you replace the "x" with 6 and then solve the problem.

so it would be -5(6+2)+3=5

Answer 12

plug the 6 back into the orignal equation

-5(6+2) + 3 =

-5(8) + 3 =

-40 + 3 = -37

6 would not be a solution to this problem

-5x - 10 + 3 = 5

-5x -7 = 5

-5x = 12

x = -12/5 is what I got solving it out
