Question

Find a solution to the linear equation 3x+y=−9.(Enter values for x and y that make the equation true.)

Answer 1

Infinite solutions, given as follows:

`y=-9-3x`

Explanation:

We have the following equation:

`3x+y=-9`

Solving for y:

`y=-9-3x`

The solution of the linear equation would be infinite, since the value of y depends on x.

For example:

when x = 0

`\begin{gathered} y=-9-3\cdot0 \\ y=-9 \end{gathered}`

One of the infinite solutions can be when x = 0 and y = -9
