One-Step Equations

Find the Solution #1

100

x + 42 = 100

x = 58

200

-32 + x = 100

x = 132

300

n - 2 = -14

n = -12

400

15 = x + (-4)

x = 19

500

x - (-40) = 190

x = 230

What do I do?

100

x + 6 = 20

Subtract 6

200

7g = 84

Divide by 7

300

7 ÷  h = 80

Multiply by 7

400

150,000 + r = 200,000

Add 150,000

500

u - (-80) = 55

Subtract 80

What is Wrong? Correct It!

100

6 = x + 4; x = 10

x = 2

200

y - (-3) = 10; y = 13

y = 7

300

-2 = p ÷ 14; p = 28

p = -28

400

100g = 200; g = -2,000

g = 2

500

-1,000,000 = 200j; j = 500

j = 5,000

Find the Solution #2

100

x ÷ 2 = 4

x = 8

200

3x = 6

x = 2

300

24g = 48

g = 2

400

-20 = p ÷  -15

p = 300

500

6 = k ÷ 19

k = 114
