`-6+x-3 \\x =2\\\\-6+2-3\\\\\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations}\\\\\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:\\-6+2=-4\\\\=-4-3\\\\=-7`

Answer 2

-7

Explanation:

So we have the expression:

`-6+x-3`

And we want to evaluate it when x is 2.

So, substitute in 2 for x:

`=-6+(2)-3`

Add the first two terms:

`=-4-3`

Subtract:

`=-7`

And that's our answer :)
