Explanation:

A)

1. Subtract 11 on both sides: y = 11

A is incorrect

B)

1. Subtract 18 on both sides: -10 = -y
2. Divide -1 on both sides: 10 = y
3. Rewrite: y = 10

B is correct

C)

1. Divide 6 on both sides: 10 = y
2. Rewrite: y = 10

C is correct

D)

1. Multiply 5 on both sides: y = 20

D is incorrect
