Question

5x+3y=-125x+3y=9i need to solve both equations and graph both lines.

Answer 1

Given:

`\begin{gathered} 5x+3y=-12\ldots\ldots\ldots\ldots(1) \\ 5x+3y=9\ldots\ldots\ldots\ldots(2) \end{gathered}`

To solve for x and y:

Subtract (2) from (1) we get,

`0=-21`

But, we know that,

`0\\e-21`

So, the system has no solutions.

Then, the graph is,

Since the lines are neither intersecting nor coinciding lines.

Therefore, it has no solution.
