Try to solve for x.

If you get, just throwing random numbers:

$\sf 5 = 5$
Then you have infinitely many solutions

If you get

$\sf x=3$
You have one solution.

There can never be 2 solutions.

If you get
$\sf 0 = -2$
since that isn't equal, you have 0 solutions.

to start of you need to change the x to 0 in the equation.
5(0)+10=5(0)-8 
then multiply by 5
0+10=5(0)-8 
do you follow so far?
