Chapter 3 - Solving Inequalities - 3-2 Solving Inequalities Using Addition or Subtraction - Practice and Problem-Solving Exercises - Page 175: 49

The two inequalities are equivalent.

We start with the expression $c+7\gt33$. In order to isolate the variable c, we must undo the addition by subtracting 7 on both sides. This gives us the expression $c\gt26$. This is the same as the second expression given, so we know that the two inequalities are equivalent.
