Answer to Question #3706 in Algebra for keshavkr
Question #3706
Solve for x and y
√ x + y =11
x+√y=7
√ x + y =11
x+√y=7
Expert's answer
√ x + y =11
x+√y=7
x = (11 - y)2
y = (7 - x)2
x = 121 - 2y +y2
y = 49 - 2x + x2
y = 49 - 2(121 - 2y +y2)+ (121 - 2y +y2)2
-y4 + 4y3 - 244y2 + 481y = 14448
This equation has complex solutions.
