3v-15+5v+3=4v
Use the distributive property to multiply v-5 by 3.
8v-15+3=4v
Combine 3v and 5v to get 8v.
8v-12=4v
Add -15 and 3 to get -12.
8v-12-4v=0
Subtract 4v from both sides.
4v-12=0
Combine 8v and -4v to get 4v.
4v=12
Add 12 to both sides. Anything plus zero gives itself.
v=\frac{12}{4}
Divide both sides by 4.
v=3
Divide 12 by 4 to get 3.
