Which linear system of equation does the matrix represent

[2 -3=10]
[5 6=-12]

is it
{2x + 5y =10
{5x + 6y =-12

no. the left matrix is the set of coefficients. You have

2x-3y = 10
5x+6y = -12

unless there's a typo somewhere.

Actually, the "matrix" is bogus. The real equation would be

(2 -3)(x)
(5 6) (y)
=
(10)
(-12)

sorry for the formatting
The multiple choice answers for the Matrix above

a. 2x-3y=10
5x+6y=12

b. 2x-3y=10
5x+6y=12

c. 2x=5
-3x=6
10x=-12

d 2y=5
-3y=6
10y+-12
how come (a) and (b) are the same? I suspect a typo, meaning one of them should look my solution.
You are not worthy as my opponent
