460+x=2\left(y+10\right)
Subtract 40 from 500 to get 460.
460+x=2y+20
Use the distributive property to multiply 2 by y+10.
x=2y+20-460
Subtract 460 from both sides.
x=2y-440
Subtract 460 from 20 to get -440.
460+x=2\left(y+10\right)
Subtract 40 from 500 to get 460.
460+x=2y+20
Use the distributive property to multiply 2 by y+10.
2y+20=460+x
Swap sides so that all variable terms are on the left hand side.
2y=460+x-20
Subtract 20 from both sides.
2y=440+x
Subtract 20 from 460 to get 440.
2y=x+440
The equation is in standard form.
\frac{2y}{2}=\frac{x+440}{2}
Divide both sides by 2.
y=\frac{x+440}{2}
Dividing by 2 undoes the multiplication by 2.
y=\frac{x}{2}+220
Divide 440+x by 2.
