Verified Answer :

2x - 6 + 5x = 10x + 30
(Distributive Property)
7x - 6 = 10x + 30

(Subtract 7x and 30 from both sides)

10x - 7x
-6 - 30
-36 = 3x
(divide by 3 to both sides
x = -12

If you would like to solve the equation 2 (x - 3) + 5 x = 5 (2 x + 6), you can calculate this using the following steps:

2 (x - 3) + 5 x = 5 (2 x + 6)
2 x - 2 3 + 5 x = 5 2 x + 5 6
2 x + 5 x - 5 2 x = 5 6 + 2 3
7 x - 10 x = 30 + 6
- 3 * x = 36    /(-3)
x = 36 / (-3)
x = - 12

The correct result would be d. - 12.
