Answer:
My guess would be
C. multiplicative identity property
Y should also be halved.
For example, if x=4 and y=2, x=2y.
If x is halved for x=2, you get 2=2y, or y=1, which is still one half of x, so the proportion remains the same.
Answer:
8
Step-by-step explanation:
Step 1: Set up equation
-1 = 7 - x
Step 2: Subtract 7 on both sides
-8 = -x
Step 3: Divide both sides by -1
x = 8
So 7 subtracted by 8 equals -1.
