Answer 5

Work with the part in parenthesis first. x + 2x gives you 3x. 3y - y gives you 2y. The center now equals 3x+2y. But you cant forget about the *3, making it 3(3x+2y)

Answer 6

so x is 1

Answer 7

Then, you multiply 3x*3 getting 9x. And 2y*3 getting 6y.

Answer 8

x does not have a value. x=x

Answer 9

soso add 9x + 6y?

Answer 10
