Answer 2

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

              Given data:- $x=1.$

              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 RHS and LHS.

• 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,

             $2x^{2} +3x-5\\=2(1^{2} )+3(1)-5\\=0.$

           Hence we will get the value $0.$
