Substitute each value from the given set for the variable one at a time into the equation and evaluate if it is true or false.
m=9
Practice makes perfect
We want to verify if any values from the given set are solutions of this equation. We will replace the variable with each value from the set and check if the equation is true for any of them.
m
4=36 Ă· m
Simplify
True or False?
4
4? =36 Ă· 4
4 ≠9
False
6
4? =36 Ă· 6
4 ≠6
False
8
4? =36 Ă· 8
4 ≠4.5
False
9
4? =36 Ă· 9
4 = 4
True
The equation is true when m=9; therefore, this is a solution of the equation.
