Answer 2

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

              Given data:- $-y=9-12.$

              To find:- Value of the expression.

              Solution:-

• Here we will use the transposition method.

• Transposition is one of the linear equations.

• To solve the transposition method we will 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,

                  $=>-y=9-12\\=>-y=-3\\=>y=3$

       Hence we will get the value $y=3.$
