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:

$\dfrac{-1}{5}(5x+20)-\dfrac{1}{4}(4x-28) = \dfrac{-1}{5}\cdot 5x + \dfrac{-1}{5}\cdot 20 + \dfrac{-1}{4} \cdot 4x + \dfrac{-1}{4} \cdot (-28)$

This equals

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