-3w-5(4x-4w)-4x
multiply the bracket by -5
(-5)(4x)=-20x
(-5)(-4w)=20w
-3w-20x+20w-4x
-3w+20w-20x-4x ( combine like terms)
answer:
17w-24x or -24x+17w
5. x = 9
6. x = 8
Just solve by simplifying both sides of the equation and then isolating the variable.
4+28= 32
Think of it as you have 28 apples and someone gave you 4 how many would you have
2 1/2 would be the simplest form i think
