x+3x=25y
Add 3x to both sides.
4x=25y
Combine x and 3x to get 4x.
\frac{4x}{4}=\frac{25y}{4}
Divide both sides by 4.
x=\frac{25y}{4}
Dividing by 4 undoes the multiplication by 4.
25y-3x=x
Swap sides so that all variable terms are on the left hand side.
25y=x+3x
Add 3x to both sides.
25y=4x
Combine x and 3x to get 4x.
\frac{25y}{25}=\frac{4x}{25}
Divide both sides by 25.
y=\frac{4x}{25}
Dividing by 25 undoes the multiplication by 25.
