Question

Find anexpression which represents the sum of (-6x + 6) and (-3x – 7) insimplest terms.

Answer 1

We are asked to find the sum of the following expressions

`(-6x+6)\: \: and\: \: (-3x-7)`

First of all, expand the parenthesis

`\begin{gathered} (-6x+6)+\: (-3x-7) \\ -6x+6-3x-7 \end{gathered}`

Now, collect the like terms together and add/subtract

`\begin{gathered} -6x+6-3x-7 \\ (-6x-3x)+(6-7) \\ (-9x)+(-1)_{} \\ -9x-1 \end{gathered}`

Therefore, the sum of the given expressions in the simplest form is

`-9x-1`
