-2x -3y = 8
-2x + 4y = 22
2 answers:
-1(-2x-3y=8) 》2x+3y=-8
2x+3y=-8
+ 》7y=14 》y=2
-2x+4y=22
-2x-6=8 》x=-7
-2x + 4y = 22
-2x - 3y = 8
Subtract 2nd from 1st equation,
7y = 14
y = 14/7 = 2
Substitute it in 1st equation,
-2x + 4(2) = 22
-2x = 22 - 8
x = -14/2
x = -7
In short, Your Answer would be (-7, 2)
Hope this helps!
