Question

What is the simplified expression for the expression below? -1/5(5x+20)-1/4(4x-28)

–2x + 3
–2x – 3
–2x – 8
–2x + 8

Answer 1

You need to distribute the numerical factors for each term in the parenthesis:

`(-1)/(5)(5x+20)-(1)/(4)(4x-28) = (-1)/(5)\cdot 5x + (-1)/(5)\cdot 20 + (-1)/(4) \cdot 4x + (-1)/(4) \cdot (-28)`

This equals

`-x-4-x+7 = -2x+3`

Answer 2

-2x+3
