Question

Let A =[12−21] using −1 solve the following system of linear equation x-2y = -1 2x+y =2.

Answer 1

Answer:

$x - 2y \\ = - 12x + y = 2 \\ = - 12( - 1) + y = 2 \\ = 12 + y = 2 \\ = y = 2 - 12 \\ = y = - 10$

Here is the correct answer mate..

Thank you ☺✌..

Answer 2

x - 2y

-12x+y= 2

-12(-1)+y=2

12+y = 2

y=2-12

y= -10

x=-1

x=-10
