Question

Jose worked 2.5 hours more than William. Together, they worked a total of 22 hours. William worked h hours.

h + 2.4 = 22

h + (h + 2.5) = 22

h + (h - 2.5) = 22

h + 5 = 22

Answer 1

All answers have 22 as their total, which means that we have to sum up their hours of work.
William + Jose.
William=h
Jose is 2.5 more than William.
So Jose is h+2.5
Together they are h+(h+2.5)=22
