Exercise 2 Page 246

Substitute each value of c one at a time into the equation to verify if it is true or false.

c=33

Practice makes perfect

We want to verify if any of the given values of c 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.

c	c-8=25	Simplify	True or False?
17	17-8? =25	9 ≠ 25	False
28	28-8? =25	20 ≠ 25	False
33	33-8? =25	25 = 25	True
35	35-8? =25	27 ≠ 25	False

The equation is true when c=33. This means that c=33 is the only solution to the equation out of the given values.
