y-1=-x-4
To find the opposite of x+4, find the opposite of each term.
-x-4=y-1
Swap sides so that all variable terms are on the left hand side.
-x=y-1+4
Add 4 to both sides.
-x=y+3
Add -1 and 4 to get 3.
\frac{-x}{-1}=\frac{y+3}{-1}
Divide both sides by -1.
x=\frac{y+3}{-1}
Dividing by -1 undoes the multiplication by -1.
x=-\left(y+3\right)
Divide y+3 by -1.
y-1=-x-4
To find the opposite of x+4, find the opposite of each term.
y=-x-4+1
Add 1 to both sides.
y=-x-3
Add -4 and 1 to get -3.
