Q:
3x + 2y = 7 x - y + 3 = 0 What is the resulting equation? 3x - y - 3 + 2y = 7 3(y - 3) + 2y = 7 3y - 3 + 2y = 7
Accepted Solution
A:
I'm not comfortable with having two " = " signs in the same equation, at least not in this situation.
You apparently meant to type in the system of linear equations
3x + 2y = 7
x - y = -3
but did not separate 3x + 2y = 7 and x - y = -3 with a comma as required.
I will assume that you meant to share:
3x + 2y = 7
x - y = -3 This system of linear equations has a solution, but there
will be no "resulting equation."
Please ensure that you have copied down this problem exactly as it was originally presented. Explain what we are to do with
3x + 2y = 7 x - y + 3 = 0: How do we interpret this?
