Answer:

x=-15/8 or -1 7/15 OR x=-5/3 or -1 2/3

Step-by-step explanation:

Subtract 15 from both sides

8x=-15

Divide 8 on both sides

Now you get your answer

x=-15/8 or -1 7/15

OR

Combine like terms

9x+15=0

Subtract 15 from both sides

9x=-15

Divide 9 from both sides

x=-15/9

Simplify

x=-5/3 or -1 2/3
