Question

A can do a piece of work in x days and B can do the same work in (x+16) days. If both working together can do it in 15 days,calculate x.

Answer 1

Answer:

`-0.5 im pretty sure this is wrong

Step-by-step explanation:

A= x days

B = (x + 16 )days

           A+B = 15 days

        = x + (x + 16) = 15

        = 2x + 16 = 15

        = 2x = +15 - 16

         = 2x= -1

        = x = -1/2

         = x = -0.5 days
