Answer 2

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

            Given data:- $2-89+x=15.$

            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 get,

           $2-89+x=15\\x+2-89=15\\x=87+15\\x=102.$

      Hence we will get the value $x=102.$
