Solve for y(addition,+)

100

y + 5 = 8

y = 3

200

3 + y =16

y = 13

300

y + 2 = 20

y = 18

400

7 + y = 33

y = 26

500

y + 13 = 36

y = 23

Solve for y(subtraction,-)

100

y - 3 = 3

y = 6

200

y - 1 = 8

y = 9

300

5 - y = 3

y = 2

400

y - 5 = 6

y = 11

500

15 - y = 8

y = 7

Solve for y(multiplication,x)

100

y x 9 = 0

y = 0

200

2 x y = 4

y = 2

300

5 x y = 20

y = 4

400

10 x y = 100

y = 10

500

y x 7 = 49

y = 7

Solve for y(division,÷)

100

y ÷ 4 = 5

y = 20

200

y ÷ 2 = 8

y = 16

300

y ÷ 5 = 6

y = 30

400

y ÷ 9 = 9

y = 81

500

y ÷ 8 = 7

y = 56
