Answer:
x can be all real numbers
Step-by-step explanation:
x - 12 ≤ 44 + x
Subtract x from both sides.
-12 ≤ 44
This statement is true, so the inequality is true for all values of x.
Now let's see how this makes sense. Look at the original inequality.
x - 12 ≤ 44 + x
Rewrite as:
x - 12 ≤ x + 44
What does there inequality mean? Subtract 12 from a number, and compare that with adding 44 to the same number. Of course, a number minus 12 is always less than the same number plus 44. It makes sense that this inequality is true for all values of x.
