Explanation:
the answer to what question ?
is the request to find (solve for) x ?
if so, we have
(-3(2x - 6) + 5x)/6 = 7 + (2(-4x + 1) - 6)/3
now, I usually remove the fractions first by multiplying both sides with both denominators :
1. multiply by 6
-3(2x - 6) + 5x = 42 + 6(2(-4x + 1) - 6)/3
2. I can skip the general multiplication by 3, because the denominator 3 goes away in interaction with the new factor 6
-3(2x - 6) + 5x = 42 + 2(2(-4x + 1) - 6)
now, we do all the multiplications and see what we get :
-6x + 18 + 5x = 42 + 2(-8x + 2 - 6) =
= 42 - 16x + 4 - 12
-x + 18 = -16x + 34
15x = 16
x = 16/15
