Question

Find an expression which represents the difference when (-4x - 2) is subtracted from (-8x + 3) in simplest terms.

Answer 1

$\begin{gathered} (-8x+3)-(-4x-2) \\ -8x+3+4x+2 \\ \text{Add like terms:} \\ (4x-8x)+(3+2) \\ 5-4x \end{gathered}$

-----------------------------------------------------

$\begin{gathered} (-4x+6y)-(9x-8y) \\ -4x+6y-9x+8y \\ \text{add like terms:} \\ (-4x-9x)+(6y+8y) \\ -13x+14y \end{gathered}$
