Provide an appropriate response.Write a system of two equations in two variables that would be most easily solved using the substitution method. Explain why substitution would be a better method to use than elimination in this case. Do not attempt to solve the system.
What will be an ideal response?
Answers will vary.
2x - 3y = 8,
y = 3x + 1.
Since the y-variable is already isolated in the second equation, solving by substitution would require fewer steps than solving by elimination. Thus, substitution is a better method than elimination in this case.
