The biggest possible set is

.
The question to ask yourself is: is the operation

<em>not valid for some values of x ? ("not valid" = impossible to compute)
</em>After removing all invalid values of <em>x </em>(if any), you have obtained the domain.<em>
</em>
We first get rid of the fraction by multiplying both sides by 10
this gives us: -70+10x=x-160
subtract x from both sides
this gives us: =-70+9x=-160
add 70 to both sides
this gives us 9x=-90
divide both sides by 9
this gives us x=-10
