Question

Naomi solves a system of equations using substitution. The system has infinitely many solutions. Which of the following could be the last step in Naomi's solution? A. x = 0 B. 3 = –3 C. 2 = 2 D. 5 = y

Answer 1

Option C) 2=2 is the last step of Naomi and it is the correct answer

Explanation:

Given that Naomi solves a system of equation by Substitution method :

The given system has infinite many solutions

Naomi's last step is 2=2

For : A system of equations after solved then its constant value must be same in both the sides

Then the system of equations has infinite many solutions

Therefore it must be 2=2

Hence option C) 2=2 is the last step and it is the correct answer
