Question

sum of two number is 75 and their difference is 35 .find the number​

Answer 1

Answer:

The numbers are 55 and 20.

Step-by-step explanation:

Let the two numbers be x and y.

x + y = 75 — eq.1

x - y = 35 — eq.2

Adding eq.1 and eq.2.

x + y + x - y = 75 + 35

2x = 110

x = 55

x + y = 75

55 + y = 75

y = 75 - 55

y = 20

The numbers are 55 and 20.

Have a nice day.
