Question

3x-7y= -28 SOLVE FOR Y

Answer 1

`y=(3)/(7)x+4`

Explanation:

`3x-7y=-28`

In order to isolate -7y we need to subtract 3x on both sides.

`-3x+3x-7y=-28-3x`

`-7y=-3x-28`

We need our variable y to be alone and positive, therefore, we need to eliminate -7, to do this, we can divide by -7

`(-7y)/(-7) =(-3x)/(-7)-(28)/(-7)`

`y=(3x)/(7)+4`
