═════════════════════

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
