4a+2b+c=y
Swap sides so that all variable terms are on the left hand side.
4a+c=y-2b
Subtract 2b from both sides.
4a=y-2b-c
Subtract c from both sides.
4a=y-c-2b
The equation is in standard form.
\frac{4a}{4}=\frac{y-c-2b}{4}
Divide both sides by 4.
a=\frac{y-c-2b}{4}
Dividing by 4 undoes the multiplication by 4.
a=\frac{y}{4}-\frac{b}{2}-\frac{c}{4}
Divide y-2b-c by 4.
4a+2b+c=y
Swap sides so that all variable terms are on the left hand side.
2b+c=y-4a
Subtract 4a from both sides.
2b=y-4a-c
Subtract c from both sides.
2b=y-c-4a
The equation is in standard form.
\frac{2b}{2}=\frac{y-c-4a}{2}
Divide both sides by 2.
b=\frac{y-c-4a}{2}
Dividing by 2 undoes the multiplication by 2.
b=\frac{y}{2}-\frac{c}{2}-2a
Divide y-4a-c by 2.
