1.
`- 5x - y = 8`

Solve for x

`-5x-y=8`

`-5x=8+y`

`-5x=y+8`

`(-5x)/(-5)=(y+8)/(-5)`

`x=(y+8)/(-5)`

`x=(-y-8)/(5)`

Solve for y

`-5x-y=8`

`-y=8+5x`

`-y=5x+8`

`(-y)/(-1)=(5x+8)/(-1)`

`y=(5x+8)/(-1)`

`y=-5x-8`

────────────────────

2.
`-4x-y=2`

Solve for x

`-4x-y=2`

`-4x=2+y`

`-4x=y+2`

`(-4x)/(-4)=(y+2)/(-4)`

`x=(y+2)/(-4)`

`x=-(y)/(4)-(1)/(2)`

Solve for y

`-4x-y=2`

`-y=2+4x`

`-y=4x+2`

`(-y)/(-1)=(4x+2)/(-1)`

`y=(4x+2)/(-1)`

`y=-4x-2`
