Answer:

Answer:

v=-13/10

Step-by-step explanation:

Our equation: [tex]3v+1+7v=-12[/tex]

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:

[tex]10v+1=-12[/tex]

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:

[tex]10v=-13[/tex]

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:

[tex]v = -\frac{13}{10}[/tex]

Hope this helps! :3
