No solution

Explanation:

First push all the variables to one side. We get,

9x-8x-x9x8xx = -12-1121

we get,

00 = -1313

This however is not possible. This means that the equation has no solution

There are no solutions

Explanation:

12-x=8x-1-9x12x=8x19x

12-x = -x - 112x=x1

Add xx on both sides

12 - x + x = -x - 1 + x12x+x=x1+x

12 = -112=1

Then subtract 1212 from both sides

12 - 12 = -1 -121212=112

0=130=13

Thus,

There are no solution!
