<h2>Answer:</h2>

The steps that could be used to solve by substitution is:

                    6x + 2(−2x + 1) = 22

<h2>Step-by-step explanation:</h2>

Substitution method--

The method of substitution states that from a equation the value of one variable is substituted in form of the other variable into  the other equation.

From the first equation we have the value of y in terms of x as:

               y = -2x + 1

Also, we have equation (2) as:

6x + 2y = 22

Hence, on putting the value of y we have:

                     6x+(-2x+1)=22

A and B are not independent events because P(A/B)=0.375 and P(A)=0.25

Step-by-step explanation:

Let A be the event that the person rides the bus to school, then:

P(A)=75/300

P(A)=0.25

Let B be the event that the person has 3 or more siblings, then:

P(B)=24/300

P(B)=0.25


P(A/B)=9/24

P(A/B)=0.375


Like P(A/B)=0.375 is different to P(A)=0.25 the events are not independent
