Step-by-step explanation:
you distribute the 7 through the whole problem
If Nate paints the wall in 4 hours, it means that he can paint 1/4 of the wall every hour.
Similarly, if Jill paints the wall in 7 hours, it means that he can paint 1/7 of the wall in one hour.
So, together, they paint the following fraction of the wall in one hour:
.
At this rate, they need 28/11 hours to paint the whole wall, in fact, after that amount of time they paint
![\frac{11}{28}\frac{28}{11} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7B11%7D%7B28%7D%5Cfrac%7B28%7D%7B11%7D%20%3D%201%20)
i.e. the whole wall
So in the answer in point form is (2,5)
And in equation form it should be
X=2, y=5
