√x + y = 13
⇒ y = 13 - √x---(1)
& x2 + √y = 5
⇒ √y = 5 - x2
⇒ y = (5 - x2)2--(2)
Hence, for solution of given system of equations we have to draw y = 13 - √x & (5 - x2)2 on graph and have to find their intersection points.
\(\because\) There are two intersection points.
So, there is two solution of given system of equations.
