Answer: The correct option is A.
Explanation:
The system of equations is,
When solving this system of linear equations with the elimination method, we can multiply the bottom equation by 3.
This step works because according to the multiplication property of equality,
If,
... (1)
Multiplied both side by m then,
..... (2)
Then (1) and (2) are equivalent equations.
So, by multiplication property of equality, the second equation can be multiply by 3.
Therefore, he correct option is A.

Answer:
The value of x is -3.
Step-by-step explanation:
To find x, we have to put everything in base 6 and continue to simplify. Since we know that 216 is 6^3, we can replace that.
6^x = 1/216
6^x = 1/(6^3)
Now, when there is a power in the denominator, we know we can move it to the numerator by making it negative. We can do that to get the bases to match.
6^x = 1/(6^3)
6^x = 6^-3
Now that they are both put in simple base 6 systems, we can just eliminate the bases and assume that the powers are equal. This lets us know that x = -3.
