Answer:
19v
Step-by-step explanation:
3v, 7v, and 9v all have the same variable, therefor, you can add all of them up as you would regular numbers, you just have to add "v" at the end.
Answer:
no solution
Step-by-step explanation:
Given
- v +5 + 6v = 1 + 5v + 3 ← combine like terms on both sides
5v + 5 = 5v + 4 ( subtract 5 from both sides )
5v = 5v - 1 ( subtract 5v from both sides )
0 = - 1 ← not possible
Hence the equation has no solution
