According to the statement, I think it is using deductive reasoning.
Deductive reasoning uses facts,rules,definitions, or properties to reach logical conclusions from given statements.
First simplify. Combine like terms
-6n + 3n = -3n
-3n = -18
Isolate the n, divide -3 from both sides
-3n/-3 = -18/-3
n = -18/-3
n = 6 (remember, in dividing two negative numbers, the answer will be positive).
6 is your answer
hope this helps
Answer:
2 and 5
Step-by-step explanation:
a. Dilation of 2nd equation by a factor of 12
b. The systems have the same solution, as dilations do not affect overall coordinates, changing side lengths but not angles
6 gallons. 192 divided by 32 is 6!
