What is the solution to the system of equations 2x+y=2 and y= -2x-2?

finlep [7]

Answer:

NO SOLUTION

Step-by-step explanation:

Solve this system by substitution:

Replace y in the first equation with -2x - 2:

2x + (-2x - 2) = 2, or

2x - 2x - 2 = 2

0 = 4 This is not possible, so this system has NO SOLUTION.
