Question

x+√y=5
√x+y=9
find value of x & y?​

Answer 1

Answer:

Step-by-step explanation:

x+√y=5 ---------(1)

⇒√y=5-x

⇒y=(5-x)²

√x+y=9

√x+(5-x)²=9

√x=9-(5-x)²

√x= 9 -(25-10x+x²)

√x= 9-25+10x-x²

√x=-16+10x-x²

Square both side

x= 256+100x²+x^4+32x²-320x-20x³

x=x^4-20x³+32x²-320x+256

x^4-20x³+32x²-321x+256=0

Solve the equation to get value of x
