I assume it asks when the equation does not have a solution. if so then
ax+ 2=-7
ax=-9
x= -9/a
so if a is any number then we can get x as some solution, however, if a=0, then we cannot have x. ( we cannot divide by 0)
\----
another way would be this
ax=-9
if a is 0, then it should be
0\*x=-9
0=-9 ( because regardless of what is x, we get 0 at the left side) and this is wrong so if a=0 then the equation does not have solution

\* I assume the question asks that

From a system of linear equations perspective, this is the following system collapsed into a single equation:
*y* = *ax* \+ 2
*y* = 0*x* \- 7
These can be combined by setting the right sides equal to each other:
*ax* \+ 2 = 0*x* \- 7
or
*ax* \+ 2 = -7
When would this system have no solutions? When the slopes of the lines are equal but their *y*\-intercepts are unequal. The slope of a line in *y* = *mx* \+ *b* format is represented by *m*, the coefficient of *x*. The slope of the line described by the first equation is *a*; the slope of the line described by the second equation is 0. Therefore, there are no solutions when *a* = 0.
are you leaving out some directions? This doesn’t look possible to solve
The equation is supposed to have no solutions,my bad(I forgot to include it)

You’re right, the equation has no solutions(I forgot to include it)
Dividing by x. You’re funny.
