8y−9x=−3
5y−8x=10

what is x and

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.
