HELP!!???? Simplify.-7 + (-3)x + 5 + (-6)xa. 2 - 3xb. -12 - 3xc. -2 - 9xd. 12 - 9x

Answer 1

We have this expression and we have to simplify it:

`\begin{gathered} -7+(-3)x+5+(-6)x \\ -7+5-3x-6x \\ -2+\left(-3-6\right)x \\ -2-9x \end{gathered}`

The answer is c. -2-9x

2) Simplify:

`\begin{gathered} 7(7-3x)+6(x-6) \\ 7\cdot7+7\cdot(-3x)+6\cdot x+6\cdot(-6) \\ 49-21x+6x-36 \\ (-21+6)x+13 \\ -15x+13 \end{gathered}`
