Question

How do you solve `-2x+4=x-8`?

Answer 1

`x=12`

Explanation:

`"collect terms in x on the left side of the equation"`
`"and numeric values on the right side"`

`"subtract "x" from both sides"`

`2x-x+4=cancel(x)cancel(-x)-8`

`rArrx+4=-8`

`"subtract 4 from both sides"`

`xcancel(+4)cancel(-4)=-8-4`

`rArrx=-12" is the solution"`
