A) y+11=22
b)8=18-y
c) 60=6y
d) y/5=4
e+10y=20

b) 8 = 18 - y

c) 60 = 6y

Step-by-step explanation:

A)

Subtract 11 on both sides:          y = 11

A is incorrect

B)

Subtract 18 on both sides:          -10 = -yDivide -1 on both sides:               10 = yRewrite:                                         y = 10

B is correct

C)

Divide 6 on both sides:          10 = yRewrite:                                    y = 10

C is correct

D)

Multiply 5 on both sides:          y = 20

D is incorrect

The surface area would be 576 because you multiply all the numbers then multiply that number by 6
