Question

what is the value of x-3+x-4+x-5 if x is 15​

Answer 1

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

       Given data:- $x=15.$

       To find:- Value of given expression $x-3+x-4+x-5.$

       Solution:-

• To solve the above equation we will follow the BODMAS rule.

• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.

        where,

          B= bracket

         O= order of power or rules

         D= division

         M= multiplication

         A= addition

         S= subtraction

         Now put the value of x in given equation,

          $x-3+x-4+x-5\\\Rightarrow (15)-3+(15)-4+(15)-5\\\Rightarrow 33.$

         Hence we will get the value $33.$

Answer 2

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

      Given data:- $x-3+x-4+x-5.$

      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,

         $=x-3+x-4+x-5\\=3x-12.$

   Putting the value of $x$ in above equation, we get,

        $=3x-12\\=3(15)-12\\=45-12\\=33.$

  Hence, value will  be$33.$
