3x=5y+x_{1}-10y
Subtract 10y from both sides.
3x=-5y+x_{1}
Combine 5y and -10y to get -5y.
3x=x_{1}-5y
The equation is in standard form.
\frac{3x}{3}=\frac{x_{1}-5y}{3}
Divide both sides by 3.
x=\frac{x_{1}-5y}{3}
Dividing by 3 undoes the multiplication by 3.
5y+x_{1}=3x+10y
Swap sides so that all variable terms are on the left hand side.
x_{1}=3x+10y-5y
Subtract 5y from both sides.
x_{1}=3x+5y
Combine 10y and -5y to get 5y.
