Find a solution to the linear equation −2x−2y=8

Sagot :

You have the following equation:

-2x - 2y = 8

In order to find a solution for the previous equation, it is necessary to select a value of x and a value of y which makes the equation consistent.

You can notice that if you choose x = -2 and y = -2 you obtain a consistent equation, as follow:

-2x - 2y = 8

-2(-2) - 2(-2) = 4 + 4 = 8

Hence, a solution to the given equation is the point (-2,-2)
