Question

I NEED HELP FAST 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.
Substitute 9 for the variable h.
Substitute 21 for the variable h.
Simplify by adding 13 and 21.
Simplify by adding 13 and 9.
21 = 21, so 9 is a solution to the equation.

Answer 1

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

13 + h = 21

13 - 13 + h = 21 - 13

0 + h = 8

h = 8

8 ≠ 9

13 + ( 9 ) = 21

22 = 21

22 ≠ 21

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