Answer:
3(Y-2) +5Y =Y+22
3Y-6 +5Y=Y+22
3Y -6 +5Y-Y-22=0
3Y+5Y-Y-6-22=0
7Y-28=0
7Y=28
Y=28/7
Y=4

Step-by-step explanation:
Work in rates per hour. These rates can then be added to form an equation
1/13 + 1/10 = 1/x where x is the time for both working together

x = 130/23 = 5.65 hours or about 6 hours 39 minutes
