$y=-7$

Work Step by Step

We need to get the y alone. In order to cancel out division, we use multiplication, so we multiply both sides by 4 to get that $y-1=-8$. We now cancel out the subtraction by adding 1 on both sides, giving us a final answer of $y=-7$. We plug -7 in for y and confirm that our answer is, indeed, correct.
