w = 5
List two inverse operations:
(Multiplication and Division)
or
(Addition and Subtraction)
g - 9 = -3
g = 6
d/-13 = -5
d = 65
g/12 - 14 = -9
g = 60
4 times a number f is 48
4f = 48
f = 12
Solve:
2 + 5 x 6 = b
b = 32
k + 7.03 = 10.4
k = 3.37
17.4f = 52.2
f = 3
-12a + 11 = 5
a = 0.5

10 less than a number g is -18
g - 10 = -18
g = -8
5/8 + 2 1/4
2 7/8

-6.7 = k + 9.85
k = -16.55
-14.5 = t/2.3
t = -33.35
n/4.5 + 3.1 = 12.2
n = 40.95
5 less than 3 times a number d is 16
3d - 5 = 16
d = 7
