i'm sorry if this is wrong.
The first sentence is not true in general. Consider the equation
. There are no solutions. Now consider
. There is only one solution,
.
But whatever. You're asked to demonstrate that
has two solutions (which is true; the right hand side must be a positive integer in order to have two solutions). This follows immediately from the definition of absolute value, which says
So suppose
. Then
Now suppose
. Then
So two solutions to
are
.
-5n - 8(1+7n) = -8
-5n - 8 - 56n = -8
-61n = 0
n = 0
