Answer 2

• We have to evaluate the above expression by using the given data.

              Given data:- $3x+5=20.$

              To find:- Value of the expression.

              Solution:-

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

• Here we will use the transposition method.

• Transposition is one of the linear equations.

• To solve the transposition method we wi.ll Identify the variables and constants.

• Then we Simplify the equation in LHS and RHS.

• Now Simplify the equation using arithmetic operations.

        By using the transposition method.

        we get,

         $3x+5=20\\\Rightarrow 3x=20-5\\\Rightarrow 3x=15\\\Rightarrow x=\frac{15}{3} \\\Rightarrow x= 5.$

        Hence we will get the value $x=5.$
