Question

Which is the best description of the solution for 2x + 3 > 1 or 5x – 9 ≤ 6?
Answer
		
all real numbers
		
x > 2 or x ≤ -3/5
		
x > -1 or x ≤ 3
		
no solution

You have to simplify two equations by isolating the x.

2x + 3 > 1 2x > 1 - 3 2x > -2 x > -1 5x - 9 <= 6 5x <= 6 + 9 5x <= 15 x <= 3 answer is C :)

thank you[:

no problem :)

phi · Answer

after you simplify  to get
x > -1 OR x ≤ 3

the key part is the "or"

the solution is any number  bigger than -1   or   less than 3

one or both of those conditions will always be true,  so it is better to say the solution is all real numbers.

oohhh... that is true....I missed that

phi · Answer

yes.  I don't particularly like this one, because it is a bit of a trick question.  On the other hand, they want you to notice you can "simplify"  x > -1 or x ≤ 3  to just
"all real numbers"
