x² + y² = 1 x + 2y = 1 x² + y² = x + 2y x(x - 1) = y(y + 2) Solutions: x = -3/5, y = 4/5 x = 1, y = 0

Rearrange x + 2y = 1 to solve for x: x = 1-2y x² + y² = 1 substitution (1-2y)² + y² = 1 (4y² - 4y + 1) + y² = 1 5y² - 4y = 0 y(5y - 4) = 0 y = 0, ⅘ When y = 0, x = 1-2·0 = 1 When y = ⅘, x = 1-2·⅘ = -⅗ Solutions: (1,0) and (-⅗,⅘)
