Answer:
C=6
Step-by-step explanation:
The strategy that I use is inverse operations.
Add 6 to 12, as the equation has "-6". 6+12=18
Now, to find C, we simply divide 18 by 3, as the remaining equation was "3c", which is multiplication.
18/3=6
Therefore, c=6.
To ensure that the answer is correct, plug in the 6 to see if its true.
3(6)-6
18-6=12
