Answer 2

Answer:-

We will get the value of p is -21.

Step-by-step explanation:

• As per the question we have to evaluate the given data.

              Given data:- 4p+7=-21.

              To find:- Value of p.

              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,

        $4p+7=-21\\=>4p=-21-7\\=>4p=-28\\=>p=\frac{-28}{4}\\=>p=-7$

       Verification:-

       $4p+7=-21\\=>4(-7)+7=-21\\=>-28+7=-21\\=>-21=-21$

             LHS=RHS
