Question

check if x=3 is a solution of the equation 5 -2x=-1.
​

Answer 1

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

       Given data:- $5-2x=-1.$.

       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,

        Therefore,

        $\Rightarrow 5-2x=-1$

       If $x=3.$

      So,

      $\Rightarrow 5-2(3)=-1\\\Rightarrow 5-6=-1.$

   Hence. condition is satisfied.

       

Answer 2

Answer:

=> So $x = 3$ is the solution of the equation $5-2x=-1$.

Step-by-step explanation:

Given data:-

$5-2x=-1$

The value of $x$ is given as $3$,

As we have to simplify the equation in LHS and RHS.

As we have,

=> $5-2x=-1$

Now, plug the value of x as 3 in the given equation:

=> 5 - 2 ( 3 ) = -1

=> 5 - 6 = -1

=> -1 = -1

LHS = RHS

Hence, proved
