Answer 2

Given,

The sum of a number and its thrice is 20.

To find,

The value of the number.

Solution,

The value of the number will be 5.

We can easily solve this problem by following the given steps.

According to the question,

We have the sum of a number and its thrice which is 20.

Now, first, we will try to write the given word problem in the form of a linear equation.

Let's take the number to be x.

Then, the given word problem can be re-written as follows:

(x+3x) = 20

4x = 20

x = 20/4 (4 was in the multiplication on the left-hand side. So, it is in the division on the right-hand side.)

x = 5

Hence, the number is 5.
