Question

2x - 5y=0
5x - y = -23​

Answer 1

x=-5

y=-2

Explanation:

-5(2x - 5y=0) » -10x+25y=0

2(5x - y = -23) » 10x-2y=-46

= 23y = -46

divide 23 on both sides to get y=-2

then plug in -2 for y » 2x-5(-2)=0

multiply -5 and -2 to get 2x+10=0 then subtract 10 to get 2x=-10 finally divide both sides by 2 to get x=-5
