Solve the system by the elimination method. -2x + y + 6 = 0 2x + y - 8 = 0 When you eliminate x, what is the resulting equation? 2y = 2 2y = -2 y = -2

For this case we have the following system of two equations with two unknowns:

[tex]-2x + y + 6 = 0\\2x + y-8 = 0[/tex]

Adding both equations we have to eliminate the variable "x":

[tex]y + y + 6-8 = 0[/tex]

Adding common terms, keeping in mind that different signs are subtracted and the sign of the major is placed:

[tex]2y-2 = 0\\2y = 2[/tex]

Answer:

[tex]2y = 2[/tex]

Option A
