Hope it helps :)
<span>Let R=A AND (NOT B)] OR (NOT B)
If A=T, B=T
then ~B=F,
A and ~B = F
So R=F
If A=T,
B=F
~B=T
A and ~B=T
so (A and ~B) or ~B = T
etc.</span>
The difference between 2x+16=14 than 2x+16=x+14 is that you would have to solve x in two different ways like finding the first equation another way than to the second equation ( I think ).
Answer: 
Step-by-step explanation:
Given
The inequality is 
adding both side 7

Multiply both sides by 

the shaded region in the figure indicates the solution set.
