Question

Solve for y. 4/7 y + 2/7 = 6

A) y = 20
B) y = -10
C) y = 10

Answer 1

C) y=10

Explanation:

4/7y+2/7=6

7(4/7y+2/7)=7(6)

4y+2=42

4y=42-2

4y=40

y=40/4

y=10

Answer 2

C) y = 10

Explanation:

Subtract 2/7 from each side

4/7y = 40/7

Divide both sides by 4/7 (Multiply by 7/4)

y = 10
