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

3. Biancao9o3o12

So solution ?

4. ParthKohli

Solve both equations.

^ "inequalities," not "equations," Grammar Nazi. ;-)

6. Biancao9o3o12

I don't get it -_-

7. CliffSedge

Solve the inequalities as if they were equations.

8. Biancao9o3o12

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

9. ParthKohli

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

10. CliffSedge

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

11. Biancao9o3o12

So it is a solution ?

12. CliffSedge

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

13. Biancao9o3o12

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

14. CliffSedge

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

15. Biancao9o3o12

Oh so that's the equation ?

16. CliffSedge

"...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.

17. Biancao9o3o12

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

18. CliffSedge

Ok, then solve the inequalities as I explained.
