Answer:

x = 7

Step-by-step explanation:

In order to find the value of x, isolate it in the equation.

1) First, distribute the 2 to the terms inside the set of parentheses.

2 (3x - 9) = 2x + 10 \\6x - 18 = 2x + 10 \\

2) Next, move all the x terms to one side and all the other terms to the other side. Subtract both sides by 2x and add both sides by 18.

6x - 18 = 2x + 10 \\4x = 28

2) Divide both sides by 4 to finally isolate x.

4x = 28 \\x = 7

Thus, x = 7.
