3. The sum of two numbers is 15 and their difference is 3, Find the numbers by solving graphically
​

Answer 1

Answer:

Given :

sum of number = 15

difference of between 2 numbers =3

Suppose :

two numbers is = x and x +3

solution :

= x +(x+3) =15

= 2x + 3. = 15

= 2x = 15-3

= 2x = 12

= x = 12 ÷ 2

= x = 6

therefore , one number is 6 and second number is 9
