(-4-x) - (3y-9x)

= - 4 - x - 3y + 9x

= 8x - 3y - 4

Violet Flores · Answer 2

Basically, you just need to simplify it first, then combine like terms.

(-4-x) - (3y-9x)

= - 4 - x - (3y - 9x)

= - 4 - x + - 1 (3y) + - 1 (-9x)

= - 4 + - x + - 1 (3y) + - 1 (-9x)

= - 4 + - x + - 3y + 9x

= (-x + - 9x) + (-3y) + (-4)

= 8x + (-3y) + (-4)

= 8x - 3y - 4
