SOLUTION: I need to categorise these into always, sometimes and never and state why. I figured out most of them an I'm stuck with the why part for these:
q+2=q+16
2t-3=3-2t
|x| is greater

Question 879926: I need to categorise these into always, sometimes and never and state why. I figured out most of them an I'm stuck with the why part for these:
q+2=q+16
2t-3=3-2t
|x| is greater than or equal to 0
|x| is greater than or equal to x

Subtract q from both sides.
Never
.
.
.
So the original statement is true when t=3/2, so sometimes.
.
.
.
Always true because that's how absolute value function is defined.
.
.
.
True, when , because then .
True, when , because , or dividing both sides by ,
So this is true always.
