Question

How do i solve
3v + 1 + 7v = -12

Answer 1

Answer:

v=-13/10

Explanation:

Our equation:
`3v+1+7v=-12`

So, lets solve this step by step:

Step #1 - We first need to combine like terms. This means to combine the vs together. Once we combine them, we get:

`10v+1=-12`

Step #2 - Now we iscolate the variable(which in this case is v). To do this we subtract the 1 to the other side of the equation. Once we subtract the 1 to the -12, we get:

`10v=-13`

Step #3 - Finally, we must get rid of the coefficent. To do this, we divide the 10 in front of the v by 10. What we do on one side, we must do on the other, which means we must also divide the -13 by 10 as well. Now we get our answer:

`v = -(13)/(10)`

Hope this helps! :3

Answer 2

-1.3

Explanation:

3v+1+7v=-12 equation

10v+1=-12 combine like terms

10v=-13 subtract 1 from both sides

v=-1.3 divide by 10
