Question

Sum of two numbers is 81. One is twice the other.

The solution of the equation is ______.

Answer 1

The solution of the equation is 27.

Explanation:

Now, solve the equation for x,

⇒ x + 2x = 81

⇒ 3x = 81

⇒ `(3x)/3 = 81/3`  ......[Dividing both sides by 3]

x = 27

Hence, the solution of the equation is 27.
