Go up to the board and show all your work for 

x + 12 = 13

x = 1

200

X + 18 = 20

Show all your work

x = 2

300

X + 45 = 100

x = 55

400

What mistake was made below?

x + 6 = 12

-6.          -6

x = 18

They added instead of subtracted

500

x + 10 + 4 = 84

x = 70

Sub Eq

100

X - 8 = 15

x = 23

200

x - 15 = 55

x = 70

300

x - 9.3 = 75.9

x = 85.2

400

x - 12 = 102.6

x = 114.6

500

x - 56.9 = 75.8

x = 132.7

Mult Eq

100

6y = 42

x = 7

200

15d = 45

x = 3

300

10x = 10

x =1

400

2x = 15

x = 7.5

500

3x = 12.36

x = 4.12

Divide Eq

100

x/6 = 8

x = 48

200

x/10 = 15

x = 150

300

x/4.5 = 12

x = 54

400

x / 15.2 = 8.6

x = 130.72

500

x/1 = 0

x = 0
