Question

x-y=3 and xy=10 . find x+y​

Answer 1

Answer:

x = 5 , y = 2 so, x + y / 5 + 2 = 7

Step-by-step explanation:

xy = 10

5 *2 = 10

x - y = 3

5 - 2 = 3

so, x + y will be 5 + 2 = 7

Answer 2

Answer

It's 7

Step by step explanation

Only 2*5 or 5*2 and 10*1 or 1*10 makes 10. Which means the value of xy is 5 and 2 or 10 and 1. The given information says that the value of x and y is 5 and 2 as:-

1) 10 - 1 or 1 - 10 ≠ 3. So it can't be the value.

2) 5 - 2 = 3. Therefore the value of x = 5 and y = 2

Hence x+y = 5+2=7
