9x-8y=4
2x-3y=-4
solving for elimination

Use simultaneous equations;

9x - 8y = 4

2x - 3y = -4

We can rearrange the second one to say that:

2x = 3y - 4

x = 

so;

9() - 8y = 4

9(3y - 4) - 16y = 8

27y - 36 - 16y = 8

11y = 44

y = 4

We then substitute y = 4 back into an original equation

9x - 8y = 4

9x - 8*4 = 4

9x - 32 = 4

9x = 36

x = 4

Final answer;

x = 4, y = 4
