Answer:
B
Step-by-step explanation:
because when you flip it you get the other side ABC
9-2x
-Difference means subtract (9- ... )
-Twice means multiply (X)
-Twice a number x is (2x)
-You are multiplying 2 and x (2x)
56/2 = 28 + 28
28 + 6 = 34
28 - 6 = 22
34 + 22 = 56
34 - 22 = 12
Your numbers are 34 and 22
Is there any other answers? To me, none of those look correct. If you had -3 and substituted it into the equation you would get -1(-3)+3, which would turn into 3+3 which equals 6.
