Find all pairs (x,y) of real numbers such that x + y = 10 and x^2 + y^2 = 56 - 3xy. For example, to enter the solutions (2,4) and (-3,9), you would enter "(2,4),(-3,9)" (without the quotation marks).
+515 idk if this is right, here's my best shot.
this is just a system of equations:
(x=5+√69,y=5−√69x=5−√69,y=5+√69)
