Can someone please help me? I don't understand this.


A system of equations is given below:


y = –2x + 1

6x + 2y = 22


Which of the following steps could be used to solve by substitution? (4 points)



Select one:


A6x + 2(–2x + 1) = 22

B–2x + 1 = 6x + 2y

C6(–2x + 1) + 2y = 22

D6(y = –2x + 1)

Verified Answer :

Susuu

Substitution is when you take the x (or y)  value in the first equation and insert it into the second equation, and solve for both values. 

y = –2x + 1
6x + 2y = 22

Now, given the y value (first equation), we can insert that into the SECOND equation. 

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

the only choice that demonstrates the above equation is A) 

So, here's your answer ⇒ a. 6x + 2(–2x + 1) = 22 

Good luck with your assignment!
