Question

How do you solve the following system?: `x - y = -6, -2x+3y=5`

Answer 1

I found:
`x=-13`
`y=-7`

Explanation:

Isolate `x` from the first equation and substitute it into the second to find `y` as:

`x=y-6`

into the second:

`-2(y-6)+3y=5`

`-2y+12+3y=5`
`y=-7`

use this value back into the first equation:
`x=-7-6=-13`
