Question

How do you solve `- 6x + 2= - 7x - 10`?

Answer 1

`x=-12`

Explanation:

First, add `7x` to both sides.

`-6x+2+color(red)(7x)=-7x-10+color(red)(7x)`

Now, add together the `x` terms.

`(color(red)7-6)(x)+2 = (color(red)7-7)(x)-10`

`color(white)"XXXXX."x+2 = -10`

Now subtract 2 from both sides.

`color(white)"X-.X."x+2-color(blue)2=-10-color(blue)2`

`color(white)"XXXXXXX--."x=-12`
