Evaluating Expression by Substituting
Replacement Values
Instructions: Substitute the given replacement values for the variable and solve each problem.
Be sure to apply the order of operations to each problem. Show all of your work on a separate
sheet of paper.
a = 3, b = 8, c = -4
1) a + b + c =
6) (a + b)2 =
2) 6a + 5c =
7) 7a + bc =
3) 2b + 9ac
8) (a + b + c)2 =
4) abc ÷ 12 =
9) (b + c)3 =
5) 3(b + c) =
10) (a - c) + b =
Substitute and simplify.
w = -2, x = 5, y = 8, z = -7
11) wx + yz =
16) 4(y + z) + 5(w + x) =
12) 3w + 3z – xy =
17) w2 – x2 =
13) y(z + x) =
18) (yz)2 – 2wx
14) (w + x + y)3 =
19) 3wz – 2xy =
15) (z – w)3 =
20) w + (x + y +z)2 =
