Let x= the number of days that it takes to paint a house. Then would tell us how much of the house would be painted in one day.
Tyrin can paint a house in 4 days so in one day, he can paint of a house
Tahjai can paint a house in 5 days, so in one day, he can paint of a house
+ = This would tell us how much of the house they both would have finished painting in one day.
Multiply everything by 20x:
20x + 20x= 20x
5x+4x=20
9x=20
x=2 days
So it would take them 2 days which is 2.22 days
