First, distribute the (1/2) into (4x+12) by multiplying them.
The equation becomes:
2x + 6 + 5x = 30
On the left side, combine “like terms” through addition.
7x + 6 = 30
Subtract 6 from both sides:
7x = 24
Finally, get x alone by dividing both sides by 7:
x = 24/7, or if you wanted to round the decimal answer, it’s about 3.429.

Probability is 0/12 since there are no blue lollipops in the bag.
If you are saying:
(3/12) - (8/12)
Then since their denominators are the same we can subtract the numerators to get our answers.
3 - 8 = -5
Following the rule of adding and subtracting fractions, the denominators will not change unless they are different.
So: (3/12) - (8/12) = -5/12
