Answer:
x = Â 7 Â Â Â hous worked by Lillian
y  = 6    hours worked by Jacob
Step-by-step explanation:
Let call  " x  "  and  "  y  "  numbers of hours Lillian and Jacob worked respectively, then according to problem statement we have:
They both combined a total of 13 hours, therefore
x  +  y  =  13   ⇒  y  = 13  -  x
And the number of ironed shirts was  295  then we have
25*x  +  20*y  =  295
We need to solve that system of equations for  x   and   y  then
25*x  +  20 * ( 13 - x ) = 295
25*x  +  260  -  20*x  =  295
5*x  =  295  -  260
5*x  =  35
x  = 35/5
x  =  7
And  y  =  13  -  x   ⇒  y  =  13 - 7
y  =  6
