You can put this solution on YOUR website! 9x - 16y = 713 multiply by 5
19x - 10y = 887 multiply by -8 & add.
45x-80y=3565
-152x+80y=-7096
-----------------------
-107x=-3531
x=-3531/-107
x=33 answer.
9*33-16y=713
297-16y=713
-16y=713-297
-16y=416
y=416/-16
y=26 answer.
PROPOF:
19*33-10*26=887
627+260=887
887=887
