Answer:
Lillian worked 7h and Jacob worked 6h
Step-by-step explanation:
the number of hours Lillian worked are x (h)
the number of hours Jacob worked are y (h)
(0 < x,y < 13)
=> Lilian ironed: 25x (shirts)
Jacob ỉroned: 20y (shirts)
because Lillian and Jacob worked a combined 13 hours and ironed 295 shirts, we have:
![\left \{ {{x+y=13} \atop {25x+20y=295}} \right. => \left \{ {{x=7} \atop {y=6}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bx%2By%3D13%7D%20%5Catop%20%7B25x%2B20y%3D295%7D%7D%20%5Cright.%20%3D%3E%20%5Cleft%20%5C%7B%20%7B%7Bx%3D7%7D%20%5Catop%20%7By%3D6%7D%7D%20%5Cright.)
so Lillian worked 7h and Jacob worked 6h
