Solve this equation.

13 (y+7) = 3 (y-1)

Y = 9.2

Explanation:

13 (y+7) = 3 (y-1)

Distribute the 13 on the left side and the 3 on the right side.

13y+91=3y-1

Subtract the 3y to the 13y (little brother goes to the big brother always)

10y+91=-1

Subtract 91 to the right side.

10y=92

Divide by 10.

Y=9.2
