Answer:
v = [tex]\frac{10}{7}[/tex]
Step-by-step explanation:
1. Switch sides. 2 + 5v + 2v = 12
2. Add similar elements. 2 + 7v = 12
3. Subtract 2 from both sides. 2 + 7v - 2 = 12 - 2
4. Simplify. 7v = 10
5. Divide both sides by 7. [tex]\frac{7v}{7}[/tex] = [tex]\frac{10}{7}[/tex]
6. Simplify. v = [tex]\frac{10}{7}[/tex]
