Question

find the solution to the linear equation -2x + -2 y equals 8 by filling in the boxes of valid value of X and Y

Answer 1

We are given the following equation:

`-2x-2y=8`

One possible solution to this system is the point:

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

Since when replacing these two values we get:

`-2(-2)-2(-2)=8`

Solving the operations:

`\begin{gathered} 4+4=8 \\ 8=8 \end{gathered}`

Since both sides of the equation are equal, that means that the point (-2,-2) is a solution to the system.
