Question

What is the solution to 4[y - 3] + 19 = 8[2y + 3] + 7

Answer 1

`4(y - 3) + 19 = 8(2y + 3) + 7 \\ 4y - 12 + 19 = 16y + 24 + 7 \\ 4y - 16y = 24 + 7 + 12 - 19 \\ \\ - 12y = 24 \\ ( - 12y)/( - 12) = (24)/( - 12) \\ y = - 2`

HOPE THIS HELPS

Answer 2

The value of y in the equation is - 2

To solve : 4(y - 3) +19=8(2y + 3) + 7?

Open the bracket :

4y - 12 + 19 = 16y + 24 + 7

Collect like terms

4y - 16y = 24 + 7 + 12 - 19

-12y = 24

Divide both sides by - 12 to isolate y

-12y / - 12 = 24 / - 12

y = - 2

Hence, the value of y is - 2
