Answer:
9x - 13y
Step-by-step explanation:
2(3x - 2y) + 3(x - 3y)
<u>Use distributive law a(b + c) = ab + ac</u>
⇒ 2·3x - 2·2y + 3·x - 3·3y
⇒ 6x - 4y + 3x - 9y
<u>Gather like terms:</u>
⇒ 6x + 3x - 4y - 9y
<u>Combine like terms:</u>
⇒ 9x - 13y

Now we know that one job takes 18 people 22.5 hours, so 2/5 of the job would take
12x + 6 because 2 times 6 is 12 and 2 times 3 is 6
