8x+12=2x_{5}
Swap sides so that all variable terms are on the left hand side.
8x=2x_{5}-12
Subtract 12 from both sides.
\frac{8x}{8}=\frac{2x_{5}-12}{8}
Divide both sides by 8.
x=\frac{2x_{5}-12}{8}
Dividing by 8 undoes the multiplication by 8.
x=\frac{x_{5}}{4}-\frac{3}{2}
Divide -12+2x_{5} by 8.
2x_{5}=8x+12
The equation is in standard form.
\frac{2x_{5}}{2}=\frac{8x+12}{2}
Divide both sides by 2.
x_{5}=\frac{8x+12}{2}
Dividing by 2 undoes the multiplication by 2.
x_{5}=4x+6
Divide 8x+12 by 2.
