5x + 6 = 2x + 15
-2x -2x

= 3x + 6 = 15
-15 -15

=3x -9

=3x -9

Ok. 5x+6=2x+15

the first think we have to do is combine like terms. we need to put all the x on one side and all the regular numbers on the other side.
5x+6=2x+15
-6 -6
5x=2x+9
-2x -2x
3x=9

the next thing we have to do is isolate the x from the regualar numbers. since divition is the opposite of multiplication we divide to undo the division

3x=9
-- ---
3 3
x=3

Answer:

The problem is incomplete, but it is solved using a binomial distribution with $n = 8$ and $p = 0.16$

Step-by-step explanation:

For each adult who regret getting tattoos, there are only two possible outcomes. Either they say that they were too young, or they do not say this. The answer of an adult is independent of other adults, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
