Question

How do you solve 4y= -8x+16 and 2y=11x - 7?

Answer 1

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

Explanation:

You can multiply the second equation by `-2` and add the two:
`{(4y=-8x+16),(color(red)(-2xx)[2y=11x-7]):}`
`{(4y=-8x+16),(-4y=-22x+14):}` add them:
`0=-30x+30`
`x=1`
substitute back into the first equation:
`4y=-8*1+16`
`4y=8`
`y=2`
