Question

X - y = 0X + y = - 4

Answer 1

The system of equations is given to be:

`\begin{gathered} x-y=0 \\ x+y=-4 \end{gathered}`

From the first equation, we have that:

`x=y`

Therefore, we can have ordered pairs to be plotted to be:

`(-4,-4),(-2,-2),(0,0),(2,2),(4,4)`

From the second equation, we have:

`\begin{gathered} When\text{ }x=0 \\ y=-4 \\ When\text{ y}=0 \\ x=-4 \end{gathered}`

Therefore, we have the ordered pairs to be:

`(0,-4),(-4,0)`

We can plot the graph as shown below:

The solution to the system is the point where the two graphs intersect.

Therefore, the solution to the equation is given to be:

`(x,y)=(-2,-2)`
