Answer:
3
Explanation:
17-2c
Well, we know that c is 7.
17- 2(7) is the new equation
First, you follow PEMDAS, and multiply first
-2 x 7 is -14, because if the numbers are the opposite of each other (As in one is positive and the other is negative), the answer is a negative number.
Now, we have 17-14, which equals 3.
