Question

How do solve the following linear system?: `8x+24y=2 , x-7y=4`?

Answer 1

`8x+24y=2` (Consider this equation as equation 1)
`x−7y=4` (Consider this equation as equation 2)

`x=(2-24y)/8`(From equation 1)
Substitute this in equation 2
`(2-24y)/8-7y=4`
`2-24y-56y=32`
`80y=-30`
`y=-3/8`
Substitute this in equation 1
`8x+24(-3/8)=2`
`8x-9=2`
`8x=11`
`x=11/8`
