Question

Helpmiiiiiiiiiiiiiiiiiiiiiiiiii​

Answer 1

`2x - 3y = 5 - - - (a) \\ 5x = 4y + 14 \\ 5x - 4y = 14- - - (b) \\ 5 * (a) - 2 * (b) : \\ - 7y = - 3 \\ y = (3)/(7) \\ x = (22)/(7)`

Answer 2

SO not sure if you want me to solve the equation after, but if it's just asking for the matrix method then here ya go

Explanation:

SO, first equation is already in matrix form

Second equation = -5x + 4y = -14

So your answer is:

2x - 3y = 5

-5x + 4y = -14
