Have you read the instructions in your homework? First, you have to find out what x,a,b,y, and z equal.

For example (these are not the real answers just and example so don't put this down: x=7

a=4

y=2

z=6

So that makes 3x to 37.... get it? Whenever you see these ( and ) and numbers are in the middle, that means that you have to do that step first....Since x=7....That makes it (3-7) (this is number 2) So its pretty simple... That was just a little hint for you k? Good luck on your homework!

P.S. I'm in the same situation as you right now....And don't write this down because x doesn't really equal 7.
