      T = CN + F. Read the problem carefully so that you can fill in the equation with the values you know: “your total costs last month were $635” T = $635; ”Each card costs $2” C = $2/item; “you have monthly fixed costs of $125” F = $125. 635 = 2N + 125. Notice that there is one variable left in the equation.

      Evaluate Algebraic ExpressionsAlgebraic expressions may contain more than one operation. Algebraic expressions can be evaluated if the values of the variables are known. First, replace the variables with their values. Then use the order of operations to calculate the value of the resulting numerical expression. Evaluate x3 5(y 3) if x 2 and y 12.
