I need help and i would appreciate it and can you explain (That's if you can explain)
Finger [1]

Answer:

x=-2

y=-3

Step-by-step explanation:

-9x+4y = 6

9x+5y = -33

We will add these together to eliminate x

-9x+4y = 6

9x+5y = -33

----------------

0x +9y =- 27

9y = -27

Divide by 9

9y/9 = -27/9

y =-3

We still need to find x

9x +5y = -33

9x +5(-3) = -33

9x-15 = -33

Add 15 from each side

9x+15-15 =-33+15

9x=-18

Divide by 9

9x/9 = -18/9

x = -2
