Which of the following (x, y) pairs is the solution for the system of equations x + 2y = 2 and -2x +y = 16?

(-6,4)

Step-by-step explanation:

make sure x's or y's are the same and opposite signs

x + 2y = 2 and  -2x +y = 16

multiply 2 with x + 2y = 2 so that there is 2x

2 * (x + 2y = 2) = 2x + 4y = 4

2x + 4y = 4

-2x +y = 16

5y = 20

y = 4

put y = 4 back into one of the equations

-2x +y = 16

-2x + 4 = 16

-2x = 12

x = -6
