Answer:
Answer:
v=-13/10
Explanation:
Our equation:
![3v+1+7v=-12](https://img.qammunity.org/2023/formulas/mathematics/high-school/gbrjkn3v2pg88pyul35ts9r375dm1aayj1.png)
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](https://img.qammunity.org/2023/formulas/mathematics/high-school/6i19mivxpdd0n8hfa1vf1j78mm20b2hffy.png)
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](https://img.qammunity.org/2023/formulas/mathematics/high-school/kumvmtfwep9yiylqur1u9kksfllvpsovcg.png)
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)](https://img.qammunity.org/2023/formulas/mathematics/high-school/e2sv275kkjjc3kpddk1v0tkuz22odzpxfk.png)
