Solve the following system of equations by using the elimination method.

x - y = 11

2x + y = 19

(1, 10)

(-1,-1)

(12,2)

(10,-1)

the answer is (6, 1)

Step-by-step explanation:

x² + y² - 12 x - 2 y + 12 = 0

(x²-12x) + (y² - 2y) + 12 = 0

(x²-2 (6) (x) + 6²) - 6² + (y² - 2y+1) - 1+12 = 0

(x-6) ² + (y-1) ² = 5²

the center of a circle is (6, 1)
