Then, it would be:

39a-7 = 9a+5a+1+17a-6+x

39a-7 = 31a-5+x

x= 39a-31a-7+5

x = 8a-2

Solve for y in terms of x.

krek1111 [17]

<u>Answer:</u>

$y=\frac{3}{2} x+6$

<u>Step-by-step explanation:</u>

We are given the following equation and we are supposed to solve y in terms of x. It simpler terms, it means that we have to make y the subject of the equation while x being used in it as it is:

$\frac{2}{3} y-4=x$

Taking the constant 4 to the side where x is to get:

$\frac{2}{3} y=x+4$

Multiplying the denominator 3 to the other side of the equation to get:

$2y=3x+12$

Isolating y to make it the subject:

$y=\frac{3}{2} x+\frac{12}{2}\\ \\y=\frac{3}{2} x+6$
