Start by multiplying to get rid of parentheses. Then use addition/subtraction to isolate x on one side of the equation. Finally, use division to determine the value of x.
Answer:
x > 1/4
Step-by-step explanation:
Slope intercept form is y=mx+b
6x-12y=36
-12y=36-6x
y=36-6x/-12
y=0.5x-3
If the letters are considered distinct, then the number of permutations is

.
If we count either C as the same character, then we would be double-counting - to correct this, we would simply divided by the number of ways we can choose C from the available characters, or

.
