Answer:
Step-by-step explanation:
Deductive reasoning is the logic process of drawing a conclusion applying a general rule to a specific case.
To solve the equation 5x + 7 = 12 you apply this:
Rule application
Subtraction property of equality 5x = 12 - 7
Simplification 5x = 5
Division property of equality x = 5/5
Simplification x = 1.
Thus, by using the general rules to the specific equation, you ge the result x = 1, which shows that this is a case of deductive reasoning.
