Answer:
Andre's Method is the only one that works
Step-by-step explanation:
Noah's method won't work because he doesn't follow the order of operations. You can pull the the 9 out first you have to distribute the 2 first.
Elena's method doesn't work because to eliminate the 18 you must use the reverse operation it must be added not subtracted.
Andre's Method is the only one that works
-7 * 12 = -84
but
-7 + 12 = 5
