if it's basic algebra that makes it a pain to describe
do you know how to find determinants?

Answer 8

1... 3y = 6x + 12
y=2x+4

2. 2y = 4x - 2

Answer 9

I'm a bit rusty in math. Haven't been in school so I'm way behind. So no -__-

Answer 10

@Fools101 thankyou !!

Answer 11

^-^ ur welcome!!!

Answer 12

1) get all the variables on the same side of the equation
please who me what you have after that

Answer 13

show*

Answer 14

As in get rid of the 3 and the 2 next to Y?

Answer 15

not quite
like for the first one I mean make it

-6x+3y=12

see what I mean (x's and y's on the same side)?

what would the second equation be?

Answer 16

honestly, math is not one of those things you can just cram on at the last minute
if you are "way behind" Cramer's rule is going to be very difficult to describe, sorry...

Answer 17

-4x - 2y =2

Answer 18

& I'm not 'cramming'. I'm asking for help. Trying to understand more then what the online slides are showing.

Answer 19

well that is correct, so nicely done
the next step is to write the coefficients as what's called an "augmented matrix" which I will draw....

Answer 20

here is our augmented matrix:
