To determine if -3 is a solution to the equation -4x + 5 = -7, we substitute -3 for x in the equation and evaluate if both sides are equal.
Plugging in -3 for x: -4(-3) + 5 = -7 12 + 5 = -7 17 = -7
Since 17 does not equal -7, -3 is not a solution to the equation -4x + 5 = -7.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
