Can someone please help me with this I’m very confused.
1 answer:
As you can see from what I’ve drawn, 12 divided by -2 will give us -6 (12/-2=-6).
Now, ask yourself this:
3 multiplied by what makes - 6? (You have to divide) so, - 6/3= - 2. The answer is 2. So one number must be 2.
Now, what times what makes 2? 1 x 2. Since we already have 2, we just have to add 1. So the last number will be 1.

Step-by-step explanation:
Hello,
Pls post the full question next time so that we can make sure what is expected.
I assume that you want to solve for (x,y)
(1) 2x + 3y = 7
(2) 3x + 2y = 8
2*(2)-3*(1) gives
2*3x + 2*2y - 3*2x - 3*3y = 2*8 - 3*7 = 16 - 21 = -5
6x - 6x + 4y -9y = -5
-5y=-5
y = 1
and we can replace in (1)
2x + 3*1 = 7
2x = 7 - 3 = 4
x = 2
hope this helps
