\frac{2}{3}x-1=5y+x
Combine 6y and -y to get 5y.
\frac{2}{3}x-1-x=5y
Subtract x from both sides.
-\frac{1}{3}x-1=5y
Combine \frac{2}{3}x and -x to get -\frac{1}{3}x.
-\frac{1}{3}x=5y+1
Add 1 to both sides.
\frac{-\frac{1}{3}x}{-\frac{1}{3}}=\frac{5y+1}{-\frac{1}{3}}
Multiply both sides by -3.
x=\frac{5y+1}{-\frac{1}{3}}
Dividing by -\frac{1}{3} undoes the multiplication by -\frac{1}{3}.
x=-15y-3
Divide 5y+1 by -\frac{1}{3} by multiplying 5y+1 by the reciprocal of -\frac{1}{3}.
\frac{2}{3}x-1=5y+x
Combine 6y and -y to get 5y.
5y+x=\frac{2}{3}x-1
Swap sides so that all variable terms are on the left hand side.
5y=\frac{2}{3}x-1-x
Subtract x from both sides.
5y=-\frac{1}{3}x-1
Combine \frac{2}{3}x and -x to get -\frac{1}{3}x.
5y=-\frac{x}{3}-1
The equation is in standard form.
\frac{5y}{5}=\frac{-\frac{x}{3}-1}{5}
Divide both sides by 5.
y=\frac{-\frac{x}{3}-1}{5}
Dividing by 5 undoes the multiplication by 5.
y=-\frac{x}{15}-\frac{1}{5}
Divide -\frac{x}{3}-1 by 5.
