5th Grade Algebra Review

Algebraic Equations I

100

6x = 30

divide both sides by 6

x = 5

200

x -23 = 50

add 23 to both sides

x=73

300

p + 35 = 91

subtract 35 from both sides

p = 56

400

n ÷ 4 = 25

multiply both sides by 4 

n = 100

500

3x = 450

divide both sides by 3

x = 150

Algebraic Equations II

100

6j - 24 = 12

j = 6

200

8k + 19 = 35

k = 2

300

5m - 9 = 3m + 7 

m = 8

400

10n + 6 = 15n - 9

n = 3

500

10p - 4 = 8p + 16

p = 10
