100\times 2y=\left(x+60\right)\times 100
Variable x cannot be equal to -60 since division by zero is not defined. Multiply both sides of the equation by 100\left(x+60\right), the least common multiple of 60+x,100.
200y=\left(x+60\right)\times 100
Multiply 100 and 2 to get 200.
200y=100x+6000
Use the distributive property to multiply x+60 by 100.
100x+6000=200y
Swap sides so that all variable terms are on the left hand side.
100x=200y-6000
Subtract 6000 from both sides.
\frac{100x}{100}=\frac{200y-6000}{100}
Divide both sides by 100.
x=\frac{200y-6000}{100}
Dividing by 100 undoes the multiplication by 100.
x=2y-60
Divide -6000+200y by 100.
x=2y-60\text{, }x\neq -60
Variable x cannot be equal to -60.
100\times 2y=\left(x+60\right)\times 100
Multiply both sides of the equation by 100\left(x+60\right), the least common multiple of 60+x,100.
200y=\left(x+60\right)\times 100
Multiply 100 and 2 to get 200.
200y=100x+6000
Use the distributive property to multiply x+60 by 100.
\frac{200y}{200}=\frac{100x+6000}{200}
Divide both sides by 200.
y=\frac{100x+6000}{200}
Dividing by 200 undoes the multiplication by 200.
y=\frac{x}{2}+30
Divide 6000+100x by 200.
