Two-Step Equations
2a - 7 = -15
a = -4
8m - 5m = 15
m = 5
1.2x + 2.7 = 6.3
x = 3
2a - 3 > 11
a > 7
P = 2L + 2W
solve for L
L = (P - 2W) / 2
3 = -6x + 15
x = 2
6 - 2y - y = 12
y = -2
10 = 5 + 4/5w
w = 6 1/4
9y + 13 < -14
y < -3
a = b - 2c
solve for b
b = a + 2c
c/4 + 10 = 22
c = 48
2(b - 7) = 16
b = 15
2y + 7 = y - 8
y = -15
-6c + 12 > 8
c < 2/3
