Question

How do you solve the system using the elimination method for 2x - 3y = 7 and 3x + y = 5?

Answer 1

I found:
`x=2`
`y=-1`

Explanation:

You can multiply the second equation by `3`:
`{2x-3y=7`
`{color(red)(9x+3y=15` add the two together (in columns):
`11x+0=22`
so that `x=22/11=2`
substitute this back into the first equation:
`2*2-3y=7`
`y=-1`
