Question

How do you solve the system using the elimination method for 5m+2n=-8 and 4m+3n=2?

Answer 1

I found:
`m=-4`
`n=6`

Explanation:

You can multply the first equation by `-3` and the second by `2` to get:
`{-15m-6n=24`
`{8m+6n=4` add the two equatons together:
`-7m=28`
so `m=-28/7=-4` substitute this value into the first equation:
`-20+2n=-8`
`n=6`
