Question

What is this equation called?

Answer 1

`\left\{\begin{array}{ccc}3x-6y=20&|\cdot2\\2x-4y=3&|\cdot3\end{array}\right\\\left\{\begin{array}{ccc}6x-12y=40\\6x-12y=9\\\end{array}\right`

The left sides of the equations are the same and the right sides of the equations are different, therefore the system of equations is inconsistent.

Answer: B. inconsistent.
