Mason with assistant

Mason had to complete the work in 10 days. Two and a half days later his assistant arrived. Together they completed the work in next three and a half days. How many days would he need an assistant for the same work?

Correct result:

x =  8.75 d


x•(2.5+3.5) + 10•3.5 = 10•x

4x = 35

x = 354 = 8.75
