Answer
$y=-1$ is the solution of the equation.
Substitute $y=-1$ in the original equation to check whether the solution is correct.
$-12=(-1)-11$ is correct. So, the solution is verified to be correct.
Work Step by Step
Given that $-12=y-11$
Add $11$ to both sides of the equation to get
$-12+11=y-11+11$
Or $y=-1$
$y=-1$ is the solution of the equation.
Substitute $y=-1$ in the original equation to check whether the solution is correct.
$-12=(-1)-11$ is correct. So, the solution is verified to be correct.
