Question

If 18 is added to twice a number the sum is 60. Find the number.​

Answer 1

Here the condition in a question is given that when 18 is added to twice a number the sum is 60.

We have to find the number.

Let us assume the number to be x

Then, the given condition can be mathematically represented as

2x + 18 = 60

Now, we will rearrange the equation to find the value of x

2x + 18 = 60

        2x = 60 - 18

        2x = 42

          x = 42 / 2

          x = 21

Hence, the number will be 21.

Answer 2

Answer:

The value of that number is 21.

Step-by-step explanation:

Given if 18 is added to twice a number the sum is 60.

Let the number is "a".

So as per question, 18 + 2a = 60

Subtract 18 from both sides

18 + 2a - 18 = 60 - 18

2a = 42

Divide both sides by

$2a=42\\a=\frac{42}{2} \\a=21$

So the value of a is 21.
