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 $2x-51=0$.
