7v−(6−2v)=12
So normally, you work on the equation in the parenthesis first, which you have to do, but as they are different, you can't. when I was in Algebra, I was taught, "To compare or combine, you must be the same kind. " so you can't add or multiply x with y. you will see though, that you have 7v minus an equation in parenthesis. That means, you have to individually multiply them, by 7v and −1. Worked out, you get:
−42v+14v=12. Then, just add them, for −28v. remember, when subtracting, if the bigger number is negative, the whole answer will be negative. −28v=12 It's really hard to understand what −v=1 stands for, plus is would be wrong. So, multiply each side of the equation by −1 for 28v=12. Divide each side by four, for 7v=3, and further divide by seven, for v=37.
