Question

Solve the following equation. Express your answer as an integer, simplified fraction, or decimal rounded to two decimal places.

−1=−2v+15

Answer 1

v=8

Explanation:

in order to isolate the variable from the numbers, you add 2v to both sides. Then, you add 1 to both sides because you want to leave the numbers on one side, and the variables on the other. You then get 2v=16 and you divide both sides by 2 to get v by itself.

-1=-2v+15

+2v. +2v

-1+2v=15

+1. +1

2v=16

2v÷2=16÷2

v=8
