v-26+4b=16
Multiply both sides of the equation by 8, the least common multiple of 8,4,2.
-26+4b=16-v
Subtract v from both sides.
4b=16-v+26
Add 26 to both sides.
4b=42-v
Add 16 and 26 to get 42.
\frac{4b}{4}=\frac{42-v}{4}
Divide both sides by 4.
b=\frac{42-v}{4}
Dividing by 4 undoes the multiplication by 4.
b=-\frac{v}{4}+\frac{21}{2}
Divide 42-v by 4.
v-26+4b=16
Multiply both sides of the equation by 8, the least common multiple of 8,4,2.
v+4b=16+26
Add 26 to both sides.
v+4b=42
Add 16 and 26 to get 42.
v=42-4b
Subtract 4b from both sides.
