5(2x-9)+12(4+x)=18?

Question

5(2x-9)+12(4+x)=18?

Answer 1

10x-45+48+12x=18

get the "x"es on one side and the real numbers on the other side

and change positives and negitives for each number that crosses over the "=" threshold

10x+12x=18+45-48

10x+12x=18-3

simplify

22x=15

find the value of "x"

x=15/22

x=1.46

did you just make this sum up randomly?

Answer 2

5(2x-9)+12(4+x)=18?

10x-45+48+12x=18

(distribute the 5 into parenthases)

(distribute the 12 into parenthasis)

22x+3=18 (Combine like terms)

To get x one one side of the equal sign you need to subtract 3 from both sides which gives you...

22x=15

Next isolate x by dividing by its reciprocal 1/22 to both sides of the equation.

22x(1/22)=15/1(1/22)

x=15/22

Hope this helped.

Answer 4

multply into the brackets

10x-45+48x+12=18

combine like terms

58x-33=   18

       +33      +33

58x =  51

-58      -58

x = -1

Answer 5

i got x= 15/22

hope this helps.

Answer 6

10x - 45 + 48 + 12x=18

22x + 3 = 18

22x= 15

x= 15/22

Answer 7

Take it in steps.  First, multiply the segments.

5(2x-9) - 10x - 45

12(4+x) = 48 + 12x

Put those back in the original equation

10x - 45 + 48 + 12x = 18

Now add the x's and numbers

22x + 3 = 18

We need x alone, so subtract the 3 from both sides

22x = 15

Now to get x, just divide both sides by 22

x = 15/22

Answer 8

distribute the parentheses

10x-45+48+12x=18

add like terms

22x+3=18

subtrast 3 on both sides to isolate x

22x=15

divide both sides by 22

x=15/22

Answer 9

x=2.3

if you round it

Answer 10

wow im just proud of myself that i got the same answer as a lot of folks.

i got 15/22. then i was like oh no thats not right then i scrolled down and was like YAYY!

Answer 11

solve the ques. as,

=> 5(2x-9)+12(4+x)=18

=>10x - 45 + 48 +12x = 18

=>22x + 3 = 18

=>x = 15/22

Answer 12

wait is it distributive property????

or what is it!!! ???

Answer 13

Okay, I suck at maths but this is what I worked out:

5(2x-9)+12(4+x)=18

(2x-9) = ...hang on, is this 2 *multiply* -9 or 2 *X* -9??

Answer 14

the person is tring to find the value of "x".

Right?
