Answer: 4, -7
Explanation:
Plug the numbers into the variables and solve;
(6)(12) / 6+12
Multiply the values in the numerator and add the values in the denominator.
72/18
Then divide and the answer will be 4.
For the second one:
4+3 / 3-4
Add the values in the numerator and subtract the values in the denominator.
7/-1
Dividing this will make 7 a negative, so the answer is -7.
Hope that helped ^^;;
