Both Foster and Ranger are correct because subtracting 3 is the same as adding –3. If you let x = 5 in either of the expressions, you get the answer 32.

Answer:

Yes, they are both correct.

Step-by-step explanation:

Subtracting is the same as adding a negative number.

Ranger's answer was 7x-3; this is the same as 7x+(-3). This means they are both correct.
