There is no solution

Explanation:

First expand everything using the distributive property:
#9-9(x+5)-7=9+3(9-3x)-81#
#9-9x-45-7=9+27-9x-81#
Then simplify both sides and solve:
#-43-9x=-45-9x#
#-43=-45#,
But wait, -43 can't equal -45, so what this means is that no matter what value of #x# you put in, it will never fix the equation, and so we refer to this as having no solution.
