y+5=-\left(n-2\right)
Divide -3 by 3 to get -1.
y+5=-n+2
To find the opposite of n-2, find the opposite of each term.
-n+2=y+5
Swap sides so that all variable terms are on the left hand side.
-n=y+5-2
Subtract 2 from both sides.
-n=y+3
Subtract 2 from 5 to get 3.
\frac{-n}{-1}=\frac{y+3}{-1}
Divide both sides by -1.
n=\frac{y+3}{-1}
Dividing by -1 undoes the multiplication by -1.
n=-\left(y+3\right)
Divide y+3 by -1.
y+5=-\left(n-2\right)
Divide -3 by 3 to get -1.
y+5=-n+2
To find the opposite of n-2, find the opposite of each term.
y=-n+2-5
Subtract 5 from both sides.
y=-n-3
Subtract 5 from 2 to get -3.
