Question

Find the value of x, √(x-y) = 3 and √(x+y) = √13​

Answer 1

Answer: x=11 and, y= 2

Step-by-step explanation:

Given that,

√(x-y) = 3

Or, (x-y) =9

And,

√(x+y) = √13​

Or, (x+y) = 13

Si, 2x=22

Or, x=11

And, 2y = 4

Or, y=2

Answer 2

Step-by-step explanation:

Square both side - x-y =9 and x+y=169

On adding both equation

2x= 178

X = 89

Put the value of X in any equation

X+y = 169

Y= 169-89

Y =80
