Hi,

Let x represent How long will it take them to paint the barn together

Question states*** Shamus can paint the barn in 6 hours, and Ishmael can paint the barn in 7 hours.

1/6 + 1/7 = 1/x

 7x + 6x = 42

    13x = 42

      x = 4hr, time to paint the barn together

Wish You the Best in your Studies.
