time taken by a worker= 1/3 hours
time taken by the new worker= 1/5 hours
time taken to complete the work if they work together
= 1/3 + 1/5

Answer:
2 hours
Step-by-step explanation:
variable x = hours
fix it fast: 25 + 50x
do it right: 35 + 45x
25 + 50x = 35 + 45x
subtract 45x from both sides
subtract 25 from both sides
(this action cancels out 45x on the right side and 25 on the left side so you can combine like terms)
50x - 45x = 35 - 25
5x = 10
divide by 5 on both sides
x = 2
