Question

A students chose a number multiplied it by 2 then subtracted by 138 from the results than get 102 what was the number he chose?

Answer 1

Answer:

Let the chosen number be x

X multiplied by 2 and subtracted by 138

2x-138=102

2x=102+138

2x=240

X=240/2

X=120

Chosen number =120

Answer 2

Given,

A student chose a number multiplied it by 2 then subtracted by 138 from the results than get 102.

To Find,

The number =?

Solution,

We can solve the question as follows:

It is given that a students chooses a number, multiplies it by 2, then subtracts by 138 and finally gets the result as 102. We have to find the number.

Let the number be equal to x.

First, he multiplies it by 2.

$= 2x$

Next, he subtracts it by 138.

$= 2x - 138$

Finally, the result of the above equation is equal to 102.

$2x - 138 = 102$

Now, we will solve the above equation to find the value of x.

$2x - 138 = 102$

$2x = 240$

$x = \frac{240}{2} = 120$

Hence, the number is equal to 120.
