Anwar thinks of a number. If he takes away $\frac{5}{2}$ from the number, the result is 23. Make an equation.

Given:

Anwar thinks of a number and takes away $\frac{5}{2}$ from the number, the result is 23.
To do:

We have to form an equation of the given condition.

Solution:

Let the number thought by Anwar be $x$.
This implies,

$x-\frac{5}{2}=23$

Multiplying both the sides by 2, we get

$2(x-\frac{5}{2})=2(23)$
$2x-5=46$

$2x=46+5$

$2x=51$ 

$2x-51=0$

The required equation is $2x-51=0$.
