Step-by-step explanation:

Layna can paint a 350-square-foot room in 4 hours.

It takes Bebe 7 hours to paint the same room.

Let t be the total time taken by both to paint.

They are completing 1 job so the equation will be :

Further solving it we get;

t = 2.5 hours.

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
