Answer:


x = - (17)/(4)

Explanation:


6x + 3(4x - 2) = 5(2x - 8)

Expand the terms in the bracket and simplify

That's


6x + 12x - 6 = 10x - 40 \\ 18x - 6 = 10x - 40

Using the subtraction property subtract 10x from both sides of the equation


18x - 10x - 6 = 10x - 10x - 40 \\ 8x - 6 = - 40

Add 6 to both sides of the equation


8x + 6 - 6 = - 40 + 6 \\ 8x = - 34

Divide both sides by 8


(8x)/(8) = - (34)/(8)

Reduce the fraction with 2

We have the final answer as


x = - (17)/(4)

Hope this helps you
