5x+3y+10-3x=5y+4
Subtract 3x from both sides.
2x+3y+10=5y+4
Combine 5x and -3x to get 2x.
2x+10=5y+4-3y
Subtract 3y from both sides.
2x+10=2y+4
Combine 5y and -3y to get 2y.
2x=2y+4-10
Subtract 10 from both sides.
2x=2y-6
Subtract 10 from 4 to get -6.
\frac{2x}{2}=\frac{2y-6}{2}
Divide both sides by 2.
x=\frac{2y-6}{2}
Dividing by 2 undoes the multiplication by 2.
x=y-3
Divide -6+2y by 2.
5x+3y+10-5y=3x+4
Subtract 5y from both sides.
5x-2y+10=3x+4
Combine 3y and -5y to get -2y.
-2y+10=3x+4-5x
Subtract 5x from both sides.
-2y+10=-2x+4
Combine 3x and -5x to get -2x.
-2y=-2x+4-10
Subtract 10 from both sides.
-2y=-2x-6
Subtract 10 from 4 to get -6.
\frac{-2y}{-2}=\frac{-2x-6}{-2}
Divide both sides by -2.
y=\frac{-2x-6}{-2}
Dividing by -2 undoes the multiplication by -2.
y=x+3
Divide -2x-6 by -2.
