Answer:
-12
Explanation:
C - A × B - 5
A = 3
B = 4
C = 5
Substitute.
5 - 3 × 4 - 5
Solve in order of operation.
5 - 3 × 4 - 5
5 - 12 - 5
-7 - 5
= -12
Note, there is another solution if the above answer is incorrect. I did not use the order of operations, instead I solved from left to right.
5 - 3 × 4 - 5
2 × 4 - 5
8 - 5
= 3
