In order to determine which equations are equivalent to 8k = 20, simplify the equations:

A.

8k - 4 = 20 + 4

8k = 20 + 4 + 4

8k = 28

this equation is not equal 8k = 20.

B.

8k ÷ 4 = 20 ÷ 4 multiply both sides by 4

8k = 20

This equation is equal to 8k = 20

C.

8k x 3 = 20 x 3 divide both sides by 4

8k = 20

This equation is equal to 8k = 20

D.

8k + 10 = 20 + 10 subtract 10 both sides

8k = 20

This equation is equal to 8k = 20

E.

8k x 5 = 20 ÷ 5

8k = 20 ÷ 5 ÷ 5

8k = 20 ÷ 25

This is not equal to 8k = 20
