The number is 7

Given :

The difference between three times a number and five is sixteen

To find :

The number

Solution :

Step 1 of 2 :

Form the equation with given condition

Let x be the required number

Three times of the number = 3x

Now the difference between three times the number and five

= 3x - 5

Now it is given that the difference between three times a number and five is sixteen

So by the given condition

3x - 5 = 16

Step 2 of 2 :

Find the number

$\displaystyle \sf{ }3x - 5 = 16$

$\displaystyle \sf{ \implies }3x = 16 + 5$

$\displaystyle \sf{ \implies }3x = 21$

$\displaystyle \sf{ \implies }x = \frac{21}{3}$

$\displaystyle \sf{ \implies }x = 7$

Hence the required number = 7
