Given:
- Sum of 2 numbers = 26
- Difference of 2 numbers = 2
To find:
- The value of 2 numbers
Method:
Let the 2 numbers be x and y respectively
x + y = 26 →→→ (Equation 1)
x - y = 2 →→→ (Equation 2)
Adding Equation 1 and 2,
x + y = 26
[+] x - y = 2
2x = 28
2x = 28
⇒ x = 28 ÷ 2
⇒ x = 14
Now let's substitute value of x in any one of the equations
Here we have substituted in Equation 2
x - y = 2
⇒ 14 - y = 2
⇒ y = 14 - 2
⇒ y = 12
∴ The 2 numbers are 14 and 12
