We practice with Expressions...so DO NOT SOLVE FOR THE LETTER...Just put the terms together!
*some terms are constants...do the math and put them together.
*some terms have variables...only combine the terms with the exact same variable (x with x, r with r, but we can't put x and r together, nor can we put x with x squared!)
