Question

The sum of two numbers is 54 and their difference is 16 . find the numbers ​

Answer 1

Step-by-step explanation:

Let the first number be x and second be y

we get ,

x + y = 54

and , x - y = 16 [ ATQ]

adding both equation we get ,

2x = 70 , x = 35

now put the value in the first equation ,

x + y = 54

35 + y = 54

y = 19

Hence we have , x = 35 and y = 19

Answer 2

let x and y be the two numbers.

x+y=54________1

xy=16_________2

so, from eq. 1 x=54-y

putting the value of X in 2eq.,

54-y×y=16

y²=54-16

y²=38

y=6.16

So, now putting the value of y in eq.1,

x=54-6.16

x=47.84

hope this helps...
