Question

Select all expressions that represent a correct solution to the equation 6(x+4)=20

A. (20−4) ÷ 6
B. 16(20 − 4)
C. 20 − 6 − 4
D. 20 ÷ 6 − 4
E. 1/6(20 − 24)
F. (20−24) ÷ 6

Answer 1

D. 20 ÷ 6 − 4

E. 1/6(20 − 24)

F. (20−24) ÷ 6

Explanation:

6(x + 4) = 20

6(x) + 6(4) = 20

6x + 24 = 20

- 24 - 24

6x = -4

/6 /6

x = -4/6 or x = -2/3

D. 20 ÷ 6 − 4

20/6 - 4

20/6 - 24/6

-4/6 = -2/3

E. 1/6(20 − 24)

1/6(-4)

-4/6 = -2/3

F. (20 − 24) ÷ 6

- 4 / 6

-4/6 = -2/3

Hope this helps!
