Answer by stanbon(57323)   (Show Source): You can put this solution on YOUR website!what is a test value to determine whether or not a problem is a solution? ------------- If you had the inequality x < -2 a test value could be ANY number. If you select x = 7 you would substitute that for x and see if you get a true statement. For example, 7 < -2 That is not true so you would conclude that 7 is not in the solution set for the inequality. -- Further, since you might realize that 7 is greater than -2 you could conclude that ANY number greater than -2 is not in the solution set. ---------------------- Bottom Line: The test number can be ANY number. You substitute it and see if it works. If it doesn't, it's not in the solution set. ===================================== Cheers, Stan H.
