Use the linear combination method to solve the system of equations PLZ HELP I WILL GIVE BRAINLIEST AND ITS WORTH A LOT OF POINTS
, PLZZZZZZZZZZZZZZZZ
2x-3y=13
2x+4y=-8
1 answer:
2x-3y=13...(1)
2x+4y=-8...(2)
Multiply equation 2 by -1 to eliminate x
2x-3y=13
+ -2x-4y=8
—————
-7y=21
y=-3
Substitute y=-3 into equation 2
2x+4(-3)=-8
x=2
Therefore, the solution to the system is (2, -3)
