Answer:

0

Step-by-step explanation:

1. combine like terms so add 2x to -5x and 7 to 8

2.then you have -3+15=3(5+6x)-12x

3. distribute the 3 to 5, 6x, and -12x

4. -3x+15=15+18x-36x

5. combine like terms so subtract 18x from -36x

6. -3x+15=15-18x

7. subtract 15 on both sides

8. -3x=0-18x

9. subtract -18 on both sides

10. 15x =0

11. x=0
Solve for xx by simplifying both sides of the equation, then isolating the variable.
x = 0
