Question

The number -2 is a solution to which of the following inequalities?

x + 7 > 5
-3 x < 1
x - 7 < -4

Answer 1

The answer is the third one, x - 7 < 4

Explanation:

Answer 2

The answer is the third one, x - 7 < 4

To find it all you need to do is plug in -2 for x and see if the inequality is true.

When you do the math for the first one, you get 5 > 5. That is not true as 5 is equal to 5, not greater.

For the second one you get 6 < 1. Again, that is not true as 1 is not greater than 6.

Finally, you get -9 < -4 for the third one. This one is correct as -9 is a smaller number than -4.
