Question

Find the 2 numbers whose sum is
75 and difference is 15.​

Answer 1

Answer:

1) 45 + 30 = 75

45 - 30 = 15

Answer 2

Answer:

Let the numbers as x and y then,

x+y = 75

and,

x-y = 15

Using elimination method :-

We get ;

2x = 90

therefore, x = 45

putting x = 45 in any of above eqn we get,

y = 30.

Required value of x = 45 and y = 30.
