Question

A system of equations is given below:

Answer 1

Answer:

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

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

Step-by-step explanation:

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

Answer 2

The answer is A

Because this where you gonna start your substitution
