Question

50-x=3(20-x)
Solve this equation. Do anybody have the capability to do it by explaining step by step clearly. If yes, then do it and show.​

Answer 1

Given :-

$\quad \dag \quad \sf 50 - x = 3 ( 20 - x )$

To Find :-

Value of 'x'

Solution :-

We knows that ;

• a ( b $\pm$ c ) = a × b $\pm$ a × c

Using this we have ;

${ : \implies \quad \sf 50 - x = 3 \times 20 - 3 \times \bf x }$

${ : \implies \quad \sf 50 - x = 60 - 3x }$

${ : \implies \quad \sf - x + 3x = 60 - 50 }$

${ : \implies \quad \sf 2x = 10 }$

${ : \implies \quad \sf x = \cfrac{10}{2}}$

${ : \implies \quad \sf x = \cancel{\dfrac{10}{2}}}$

${ : \implies \quad \bf \blue \therefore \quad \red x \green = \orange 5 }$

Henceforth , The Required Answer Is ' 5 ' :)

Answer 2

• As per the data given in the question, we have to find the value of expression.

• Given data:-$50-x=3(20-x).$

        To find:- value of the expression.

        Solution:-

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

• Step 1:- we will Identify the variables and constants in the given simple equation.

• Step 2:-then we Simplify the equation in LHS and RHS.

• Step 3:- Transpose or shift the term on the other side to solve the equation further simplest.

• Step 4:- Simplify the equation using arithmetic operation as required that is mentioned in rule 1 or rule 2 of linear equations.

• Step 5:- Then the result will be the solution for the given linear equation.

       By using the transposition method. we get,

           $\Rightarrow 50-x=3(20-x)\\\Rightarrow 50-x=60-3x\\\Rightarrow -x+3x=60-50\\\Rightarrow 2x=10\\\Rightarrow x=5.$

     Hence, the value will be $5.$
