Answer:
v = 28/29
Step-by-step explanation:
- 9 - (18v - 5) = 2(7v - 16) - 3v
- 9 - 18v + 5 = 14v - 32 - 3v
- 18v - 14v + 3v = - 32 - 5 + 9
- 29v = - 28
v = -28 / -29
v = 28/29

the fractions are set up so that each unit cancels out until its only meters/hour
you can multiply all the numerators together to get 72000 and all the denominators to get 1
72000 meters/1 hour
72000 meters in 1 hour
hope this helped
