Well, let's take a moment to appreciate the beauty of these numbers dancing together on the canvas of mathematics. To find out what 12a equals, we can combine like terms by adding 4a and 2a to get 6a, and adding 6b and 4b to get 10b. So, 12a equals 6a plus 6a, which simplifies to 12a. Just like adding happy little trees to a painting, math can be a joyful experience when we take it step by step.
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
It is: 12a+2 when simplified
-24
12a + a - 3a = 10a
12*a+8 =12a+8
13a
18
It multiplies out as: 12a-12+2 = 12a-10
That depends what the value of a is.
