Solve for x
x = -\frac{13}{3} = -4\frac{1}{3} = -4.333333333333333
Solve for y
y = \frac{13}{3} = 4\frac{1}{3} = 4.333333333333333

3y+7-3x=20
Add 5 and 2 to get 7.
7-3x=20-3y
Subtract 3y from both sides.
-3x=20-3y-7
Subtract 7 from both sides.
-3x=13-3y
Subtract 7 from 20 to get 13.
\frac{-3x}{-3}=\frac{13-3y}{-3}
Divide both sides by -3.
x=\frac{13-3y}{-3}
Dividing by -3 undoes the multiplication by -3.
x=y-\frac{13}{3}
Divide 13-3y by -3.
3y+7-3x=20
Add 5 and 2 to get 7.
3y-3x=20-7
Subtract 7 from both sides.
3y-3x=13
Subtract 7 from 20 to get 13.
3y=13+3x
Add 3x to both sides.
3y=3x+13
The equation is in standard form.
\frac{3y}{3}=\frac{3x+13}{3}
Divide both sides by 3.
y=\frac{3x+13}{3}
Dividing by 3 undoes the multiplication by 3.
y=x+\frac{13}{3}
Divide 13+3x by 3.
