2x+y+y=50
Combine x and x to get 2x.
2x+2y=50
Combine y and y to get 2y.
2x=50-2y
Subtract 2y from both sides.
\frac{2x}{2}=\frac{50-2y}{2}
Divide both sides by 2.
x=\frac{50-2y}{2}
Dividing by 2 undoes the multiplication by 2.
x=25-y
Divide 50-2y by 2.
2x+y+y=50
Combine x and x to get 2x.
2x+2y=50
Combine y and y to get 2y.
2y=50-2x
Subtract 2x from both sides.
\frac{2y}{2}=\frac{50-2x}{2}
Divide both sides by 2.
y=\frac{50-2x}{2}
Dividing by 2 undoes the multiplication by 2.
y=25-x
Divide 50-2x by 2.
