Question

What is
5(2y+4)-11=139

Answer 1

10y + 20 -11 =139

10y = 130

y = 130 / 10

y = 13

Explanation:

Answer 2

Explanation:

5(2y + 4) - 11 = 139

5*2y + 5*4 -11 = 139

10y + 20 -11 = 139

10y + 9 = 139 {subtract 9 form both sides}

10y + 9- 9 = 139 -9

10y = 130 {Divide both sides by 10}

10y/10 = 130/10

y = 13
