Answer 3

solve for x.

Answer 4

I have a lot of trouble with linear equations. I don't understand how to do them. I need step by step instructions, but in college, I guess they figure you should already understand the basics, but I don't. :(

Answer 5

2x-42x-308=52

Answer 6

combine like terms.

Answer 7
