Person a can paint the neighbor's house 22 times as fast as person b. the year a and b worked together, it took them 77 daysdays. how long would it take each to paint the house?

Let 1/x=the time it takes for person b to paint
let 1/22x the time that it takes for person a to paint
lastly we have the following since we know that when they work together that is how long it takes

to solve we first multiply both sides by 1694x

we then combine like terms

lastly we divide both sides by 22

The answer would be d i think but i’m for sure it is not a and c
