2y+3-3=20x\times \frac{3}{4}
Combine y and y to get 2y.
2y=20x\times \frac{3}{4}
Subtract 3 from 3 to get 0.
2y=15x
Multiply 20 and \frac{3}{4} to get 15.
15x=2y
Swap sides so that all variable terms are on the left hand side.
\frac{15x}{15}=\frac{2y}{15}
Divide both sides by 15.
x=\frac{2y}{15}
Dividing by 15 undoes the multiplication by 15.
