|2x - 7| > 1
So
2x - 7 > 1
or
2x - 7 < -1

Solve the inequalities as if they were equations.

@ParthKohli if I solve them they will get the same answer

Sorry, I had an absolute value equation running in my mind. lol

Not so, one equals 1, the other equals -1.

So it is a solution ?

There are two solutions because you have two equations (inequalities).

@CliffSedge I get that but my test is only asking me if it's a solution or an inequality

Treat
2x - 7 > 1
2x - 7 < -1
As if it were
2x - 7 = 1
2x - 7 = -1
and solve both for x.

"...my test is only asking me if it's a solution or an inequality "
I don't understand that question.
You can find a solution to the statement and the solution will be an inequality.

My book says solve for each inequality. If there is no solution write no solution

Ok, then solve the inequalities as I explained.
