Respuesta :

first you distributive property:
3x-15=9
Add 15
3x=24
Divide
x=8

Answer:

x=8.

Step-by-step explanation:

You can remove the parenthesis by multiplying the 3 to everything in them. In this case, it would be 3x-15=9. You can start by adding 15 to both sides, which give us 3x=24. You can now divide 3 by both sides. The right side is 24/3 which is 8 and the left side is just x. x=8.
