one step equations

Solve the following equation

2y = 18

• y = 36

• y = 16

• y = 9

• y = 20

x + 8 = 15

• x = 23
• x = 7
• x = 120
• x = 15/8

13 + y = 20

• y = 13
• y = 33
• y = 7
• y = 20/13

n - 4 = 12

• n = 16
• n = 8
• n = 4/12
• n = 12/4

1/2 n = 10

• n = 10
• n = 5
• n = 20
• n = 12

y/3 = 8

• y = 3/8
• y = 8/3
• y = 24
• y = 83
