Each man does 2 units of work a day and each boy 3 units, and the picture shows one team that does a 12-unit job in one day. If x men and y boys also do the 12-unit job in one day, which equation must x and y satisfy?

Question

Accepted Answer

2x + 3y = 12. Men do 2x units and boys 3y units, so 2x + 3y = 12 . The team shown fits: 2(3) + 3(2) = 12 .

Each man does 2 units of work a day and each boy 3 units, and the picture shows one team that does a 12-unit job in one day. If $x$ men and $y$ boys also do the 12-unit job in one day, which equation must $x$ and $y$ satisfy?
