Final answer:
The correct evaluation of the expression 3c - 2b, when b=2 and c=6, is 14 after substituting the values and simplifying the expression. So, the correct evaluation of the expression 3c - 2b when b = 2 and c = 6 is 14.
Step-by-step explanation:
The student's question involves evaluating the expression 3c-:2b, given that b=2 and c=6. However, there seems to be a typo in the expression. Assuming the correct expression is 3c - 2b, we substitute the given values to get the following:
3(6) - 2(2) = 18 - 4 = 14
So, the correct evaluation of the expression 3c - 2b when b = 2 and c = 6 is 14.
