12a=5b-2c+26
Add 26 to both sides.
\frac{12a}{12}=\frac{5b-2c+26}{12}
Divide both sides by 12.
a=\frac{5b-2c+26}{12}
Dividing by 12 undoes the multiplication by 12.
a=\frac{5b}{12}-\frac{c}{6}+\frac{13}{6}
Divide 5b-2c+26 by 12.
5b-2c=12a-26
Swap sides so that all variable terms are on the left hand side.
5b=12a-26+2c
Add 2c to both sides.
5b=12a+2c-26
The equation is in standard form.
\frac{5b}{5}=\frac{12a+2c-26}{5}
Divide both sides by 5.
b=\frac{12a+2c-26}{5}
Dividing by 5 undoes the multiplication by 5.
