Question #3706

Solve for x and y
<br> √ x + y =11 <br>x+√y=7

Expert's answer

√ x + y =11

x+√y=7

x = (11 - y)^{2}

y = (7 - x)^{2}

x = 121 - 2y +y^{2}

y = 49 - 2x + x^{2}

y = 49 - 2(121 - 2y +y^{2})+ (121 - 2y +y^{2})^{2}

-y^{4} + 4y^{3} - 244y^{2} + 481y = 14448

This equation has complex solutions.

x+√y=7

x = (11 - y)

y = (7 - x)

x = 121 - 2y +y

y = 49 - 2x + x

y = 49 - 2(121 - 2y +y

-y

This equation has complex solutions.
