Question

Please find the answer, and try to explain how you did it. Thanks

Answer 1

Use the distributive property.

-7=5x+3x+9

Add what you can together.

-7=8x+9

Even out both sides and get rid of the 9.

-16=8x

Divide by 8 on both sides so that you only have the x.

-2=x

Then you have your answer!
