1) true 
2)false
Step-by-step explanation:
1) 5(3)+2(4) = 23 
 = 15+8=23 
 23=23
thus, (3,4) is solution for 5x + 2y = 23
2) 5(0)+2(4) =23 
= 0+8 is not 23 
thus, (0,4) is not solution for 5x + 2y = 23

If is
x > 2 or x < 7 ⇒ x is any real number
If is
x > 2 and x < 7 ⇒ 2 < x < 7
A set of all numbers that are greater than 2 and less than 7.
