-3 + 42 > 3 x > 15 x < 15 x > 13 x < 13

Ilya [14]

Answer:

Where's the x?

I am assuming that the problem must be

-3 + 42 > 3x

if that is true, then

x < 13.

As this statement is, -3 + 42 > 3 is a true statement because -3 + 42 = 39, and

39 > 3 [39 is always greater than 3]

Step-by-step explanation:

Let me know if you need a step by step.
