x+2y-5x=y+1
Subtract 5x from both sides.
-4x+2y=y+1
Combine x and -5x to get -4x.
-4x=y+1-2y
Subtract 2y from both sides.
-4x=-y+1
Combine y and -2y to get -y.
-4x=1-y
The equation is in standard form.
\frac{-4x}{-4}=\frac{1-y}{-4}
Divide both sides by -4.
x=\frac{1-y}{-4}
Dividing by -4 undoes the multiplication by -4.
x=\frac{y-1}{4}
Divide -y+1 by -4.
x+2y-y=5x+1
Subtract y from both sides.
x+y=5x+1
Combine 2y and -y to get y.
y=5x+1-x
Subtract x from both sides.
y=4x+1
Combine 5x and -x to get 4x.
