Zane is determining whether the given value of the variable is a solution of the equation.                13 + h = 21 for h = 9 What steps should Zane take? Check all that apply.

Respuesta :

Answer:

See explanation

Step-by-step explanation:

Solution:-

- There are two ways to verify whether the value of ( h ) assumed to be equal to 9 satisfies the given equation:

                           13 + h = 21

First method: Solving for ( h ) using the given equation

  1 ) Subtract ( 13 ) on both sides of the equation:

                           13 - 13 + h = 21 - 13

                            0 + h = 8

                            h = 8                

  2 ) Compare the evaluated value of ( h ) with the assumed value:

                            8 ≠ 9    

  3 ) Conclude: The given value of ( h ) is not a solution of the given equation.

 Second method: Plug and compare

   1) Plug the assumed value of h = 9 into the given equation:

                           13 + ( 9 ) = 21

                               22 = 21

   2) For the equality to be true then the both right and left hand side of the " = " must be of same numerical value:

                               22 ≠ 21

  3) Conclude: The given value of ( h ) is not a solution of the given equation.
