Find the answer, and try to explain how you did it.

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!

K= 18

Step-by-step explanation:

1 and 8 are exact opposites so they equal eachother

so

3k-7=5k+29

subtract 3k to 5k and add 7 to 29

2k=36

then divide 36 by -2

so K = 18
