Question

I need help on this problem that has to do with multiplication with elimination. I WILL FAN AND MEDAL YOU!!!
6x - 3y = 12
4x - 3y = 24

Answer 1

Well you need to get rid of one of the two variables to start so we can subtract to do that
6x - 3y = 12
-
4x - 3y = 24

which ends up being

2x = -12
so x = -6

Plugging this into the equation (second one)
4 * -6 - 3y = 24
-24 - 3y = 24
-3y = 48
y = -16

So the prove,
6 * -6 - 3 * -16 = 12
-36 - -48 = 12
(48 - 36 = 12)
12 = 12

And that's that, or at least it should be.
