You can put this solution on YOUR website!
x + 2y = 19
-x + 7y = 53
---------------Addition eliminates x find y
0 + 9y = 72
y = 72%2F9
y = 8
:
Find x using the 1st equation
x + 2(8) = 19
x + 16 = 19
x = 19 - 16
x = 3
;
3,8 is the ordered pair
;
Check solutions in the 2nd equation
-3 + 7(8) =
-3 + 56 = 53
