x^2+y^2=25, 2x+y=10, x+y=?

	Dean Bandes ⁦‪@dbandes‬⁩ ⁦‪@sonukg4india‬⁩ This is a job for analytic geometry. A circle and a line can intersect in 0, 1 (tangent), or 2 points. The circle x^2 + y^2 = 25 and the line 2*x + y = 10 intersect in two points, (3, 4) and (5, 0); so the possible sums are 5 and 7. pic.twitter.com/zXQQATQn5s   2022/09/11 10:15
