Answer:
(1,-2)
Step-by-step explanation:
2(5x-2y=9) = 10x-4y=18
3x+4y=-5
4 cancels out then u add everything together
now u have 13x=13 the u divide 13x on both sides and you'll get x=1
now u plug xin to what ever equation u want i pick 3x+4y=-5
now u have 3(1)+4y=-5 then 3+4y=-5 then u subtract 3 on both sides and you get -8
now u have 4y=-8 then u divide and u get y=-2
x=1 y=-2
(1,-2)
