A proportional change means that for every change in 1 value, it is accompanied by a change in another value that is the same every time. For example, with this, if x=1 then y=2*1=2. If we move x up 1 value to 2, y=2*2=4. Next, if we move x one more value up then 3*2=y=6. As you may notice, y adds up by 2 every time. In addition, you multiply the x value by the same number every time and only that number (no adding anything) and it is therefore a proportional equation

12 − x = 7x + 32
Arada [10]

Answer:

C. the subtraction property of equality

Step-by-step explanation:

12-x = 7x + 32

Step - 1: -x = 7x + 20

In that case, we just swap 12 from the left side to right side, and then we subtract 12 from 32 which is on the right side. Therefore, we do not multiply, divide or add anything. So, the option "C" is correct.

Step 2: -8x = 20

In that case, we again subtract 12 by interchanging the side. Moreover, we change the side of 7x to deduct it from -x.

Therefore, in both the cases, we use the subtract property of equality.
