20=8+v i dont know how to do this
You subtract 8 from both sides so the answer is v=12
20 = 8 + v equals v = 12.First, subtract 8 from both sides. Your problem should look like: 20 - 8 = vSecond, simplify 20 - 8 to get 12. Your problem should look like: 12 = v.Third, switch sides to get v = 12, which is the correct answer.
