Question

Choose the best description of its solution. If applicable, give the solution.

Answer 1

Given:

`\begin{gathered} -x-3y=-6\ldots\text{ (1)} \\ x+3y=6\ldots\text{ (2)} \end{gathered}`

Adding equation(1) and equation(2)

`\begin{gathered} -x-3y+x+3y=-6+6 \\ 0=0 \end{gathered}`

The system has infinitely many solution .

They must satisfy the equation:

`y=(6-x)/(3)`
