Question

20 by 100 = x-3 by 3 solve for x
​

Answer 1

To find : value of $x$

Given : $\frac{20}{100} = \frac{x-3}{3}$

Solution :

• Here, we will use the below following steps to find a solution using the transposition method:

1. We will Identify the variables and constants in the given equation.
2. Then we differentiate the equation as LHS and RHS.
3. We take constants at RHS leaving variable at LHS.  
4. Simplify the equation using arithmetic operation as required to find the value of $x$ .
5. Then the result will be the solution for the given linear equation. By using the transposition method. we get,

• $\frac{20}{100} = \frac{x-3}{3}$  

        $\frac{1}{5} = \frac{x-3}{3} \\1\times 3 = 5 ( x-3 ) \\3 = 5x - 15 \\3 + 15 = 5x \\ 18 = 5x \\x = \frac{18 }{5}$

Hence, value of $x$ is $\frac{18}{5}$ .
