4x-4+2\left(y-1\right)=0
Use the distributive property to multiply 4 by x-1.
4x-4+2y-2=0
Use the distributive property to multiply 2 by y-1.
4x-6+2y=0
Subtract 2 from -4 to get -6.
4x+2y=6
Add 6 to both sides. Anything plus zero gives itself.
4x=6-2y
Subtract 2y from both sides.
\frac{4x}{4}=\frac{6-2y}{4}
Divide both sides by 4.
x=\frac{6-2y}{4}
Dividing by 4 undoes the multiplication by 4.
x=\frac{3-y}{2}
Divide 6-2y by 4.
4x-4+2\left(y-1\right)=0
Use the distributive property to multiply 4 by x-1.
4x-4+2y-2=0
Use the distributive property to multiply 2 by y-1.
4x-6+2y=0
Subtract 2 from -4 to get -6.
-6+2y=-4x
Subtract 4x from both sides. Anything subtracted from zero gives its negation.
2y=-4x+6
Add 6 to both sides.
2y=6-4x
The equation is in standard form.
\frac{2y}{2}=\frac{6-4x}{2}
Divide both sides by 2.
y=\frac{6-4x}{2}
Dividing by 2 undoes the multiplication by 2.
y=3-2x
Divide -4x+6 by 2.
