Question

What is the best way to describe the solution of this system of equations

Answer 1

To understand the answer for this system the first step is to rewrite the second equation. We will isolate the "y" variable on the left side. We have:

`\begin{gathered} 3y-x=12 \\ 3y=x+12 \\ y=(1)/(3)x+4 \end{gathered}`

The second equation is the same as the first. They're colinear. This means that there are an infinite number of solutions. The correct option is "a".
