Question: One third of a number is eight less than the number.what is true number?

Solution:

In such type of equation

From the information given we need to try to form equation using one or two variables depending upon the given unknowns.

So in this problem

Given information is

One third of a number is eight less than the number.

So the unknown here is the true number.

Since here the unknown is one we will write equation in one variable with the help of given information.

Let us consider the given true number to be x

Using the information we can write the equation as

$\frac{x}{3}$ = x - 8

Is the required equation.

So solving this equation gives:-

x = 3x - 24

2x = 24

x = 12

So the true number is 12 .

Answer 2

let the no is x

now according to question
$\frac{1}{3} x = x - 8 \\ x = 3x - 24 \\ x - 3x = - 24 \\ - 2x = - 24 \\ 2x = 24 \\ x = \frac{24}{2} \\ x = 12$
the no is 12
