Answer 2

Given:

A statement:-

When 9 is added to two times a number, we get 67.

What To Find:

We have to find the number.

How To Find:

To find the number, we will

• Form an equation
• Solve the equation

Solution:

• Forming the equation.

Let the number be x.

The statement says that 9 is added to two times a number gets 67.

So,

• Two times a numbers : 2x
• 9 added to two times : 2x + 9
• Gets 67 : 2x + 9 = 67

∴ Hence, the equation is 2x + 9 = 67.

• Solving the equation.

2x + 9 = 67

Take 9 to RHS,

⇒ 2x = 67 - 9

Subtract 9 from 67,

⇒ 2x = 58

Take 2 to RHS,

⇒ x = 58/2

Divide 58 by 2,

⇒ x = 29

∴ Hence, the number is 29.
