ANSWER KEY
Basic Algebra
Determine the value of the variable in each equation.
1. 6 + a = 12

2. 7 - b = 2
a = 6 b = 5


3. 11 + 14 = c 

4.
24
d = 3

5. 10e = 110
c = 25 d = 8 e = 11


6.
f7
= 7

7. 13g = 26 8. 35 - h = 10
f = 49 g = 2 h = 25


9. 6 + i = 23 

10. j - 17 = 7 

11.
42
7 = k
i = 17 j = 24 k = 6


12. 4m = 32 

13.
72
n = 9

14. 33 + 66 = p
m = 8 n = 8 p = 99


15.
q8
= 5 „\ 5 + r = 14 - 3 „\ 11 + 4 = 3s
q = 40 r = 6 s = 5
