\fDirections: For problems 1-9 evaluate and simplify the following expressions. Remember that when writing algebraic expressions, it's best to order them from the greatest amount of variables and coefcients to the least, and also place the variables in alphabetic order. For example, it's best to write: 3 + 4X + y as 4X + y + 3. They both have the same value though regardless of the order. 1.2(x+6)4+x 2. (x+4)-9 3.y+7+87(x-8) 4.
