Answer:

x=-8

Explanation:

The reason why x is -8 is because

The first step is to isolate the x

To isolate the x you got to add 12 to both sides


(3)/(4)x-12+12=-18+12

the -12 gets canceled out by the positive twelve so all thats left now is


(3)/(4)x=-18+12,-18+12 is -6 so its
(3)/(4)x=-6

The second step is to divide

now you have to divide by
(3)/(4) on both sides


\frac{(3)/(4) x}{\frac{3}4} } =(-6)/((3)/(4) )

which
(3)/(4) is taken out on the left side because its divided by itself so all thats left is a one,while on the right side -6 divided by three-fourths is -8

Answer:

x = -8

Explanation:

Add 12 on both sides

You get 3/4x = -6

Multiply 4/3 on both sides

You get x = -24/3

Simplify and you get -8.
