8x=13+8y+11
Add 11 to both sides.
8x=24+8y
Add 13 and 11 to get 24.
8x=8y+24
The equation is in standard form.
\frac{8x}{8}=\frac{8y+24}{8}
Divide both sides by 8.
x=\frac{8y+24}{8}
Dividing by 8 undoes the multiplication by 8.
x=y+3
Divide 24+8y by 8.
13+8y=8x-11
Swap sides so that all variable terms are on the left hand side.
8y=8x-11-13
Subtract 13 from both sides.
8y=8x-24
Subtract 13 from -11 to get -24.
\frac{8y}{8}=\frac{8x-24}{8}
Divide both sides by 8.
y=\frac{8x-24}{8}
Dividing by 8 undoes the multiplication by 8.
y=x-3
Divide -24+8x by 8.
