Question

info about the problems: I need the solved in y=mx+b form, and I need work showed in detail. thanksx +6y =187x + 14y =21- 3x - 4y =1212x - y =16

Answer 1

1.

`x+6y=18`
`6y=18-x`
`y=-(1)/(6)x+3`

2.

`7x+14y=21`
`14y=-7x+21`
`y=-(1)/(2)x+(3)/(2)`

3.

`-3x-4y=12`
`4y=-3x-12`
`y=-(3)/(4)x-3`

4.

`12x-y=16`
`y=12x-16`
