step-by-step explanation:
8y-9x=-3
5y-8x=10
8y=-3+9x
y=8/9x -3/8
5y=8x+10
y=8/5x+2
8/5x+2=8/9x -3/8
8/5x=8/9x -2 3/8
32/45x=-2 3/8
32x=-106 7/8
x=-3 87/256
5y=-26.71875 +10
y=-5.34375+2
y=-3.34375
now plug back in to check
5(-3.34375) −8(-3.33984375)=?
5(-3.34375) −8(-3.33984375) =10
hence we are right.
