Hello:
x²+y²=25 ... (1)
, 2x+y=10 ... (2)
by (2) : y = 10 - 2x
subsct in (1):
x² + (10-2x) ² = 25
x² + 100 - 20x + 4x² = 25
5x²-20x + 75 = 0
x² - 4x + 15 = 0
(x+3) (x-5) = 0
x+3 = 0 or x-5 = 0
x = - 3 or x = 5
if x = - 3 y = 10 - 2 (-3) = 16
if x = 5 y = 10-2 (5) = 0
two solutions : (-3, 16), (5, 0)
