Method 1: By Listing Multiples
List out all multiples of each denominator, and find the first common one.
Multiples of 3 : 3, 6, ...
Multiples of 2 : 2, 4, 6, ...
Therefore, the LCD is
6
6.
Method 2: By Prime Factors
Since
3

3,2 are prime numbers themselves, we simply multiply them to get the LCD.
Therefore, the LCD is

=

Answer:

Step-by-step explanation:

-3 < 2x + 3 <= 5

-6 < 2x <= 2

-3 < x <= 1

such a condition is an "and" condition. both parts need to be fulfilled.

-3 < x and x <= 1

if you are still not seeing it :

-3 < x is the same as x > -3
