d=26
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.
d | d+9=35 | Simplify | True or False? |
---|---|---|---|
16 | 16+9=?35 | 25=35 | False |
22 | 22+9=?35 | 31=35 | False |
26 | 26+9=?35 | 35=35 | True |
36 | 36+9=?35 | 45=35 | False |
The equation is true when d=26; therefore, this is a solution of the equation.
