thanks for the answer but if you don't have any problem, can you send me the solution?
let x be the days he work and let y be the days he is absent
x+y=30, 200x-20y=3800
now, u substitute the value of x in the second equation using the first equation...from x+y=30, it will become x=-y+30
200x-20y=3800--- -200(-y+30)-20y=3800
-200y+6000-20y=3800
-220y=3800-6000
-220y=-2200.....y=10 days
thank you so much
no problem!
