Is 7-x the same as x-7

math,

Report as

no
7-x= -x+7
because any number without a +/- before is positve, so when flipping the order around, draw all the signs in first, so
+7-x=7-x and now you can convert it into addition, then flip it because order doesnt matter in addition
7-x=-x+7

The equation 7-x is not the same as x-7. This is because the end result cannot be the same as one will be positive and the other will be negative. For instance, suppose the value of x is 2, 7-x will be 5 while x-7 will be -5.

No. Think of x as any number, we'll use 4 as an example. 7-4 is not the same as 4-7.

However 7-x is the same as -x+7.

No, it's not. Here's how: lets make the X a 3, and now your equation is 7 - 3, which equals 4. Now lets switch the equation around, which you think is the same: 4 - 7, which equals -3. So no, they're not the same.

No. Let's pretend x=2, so 7-x would equal 5, and x-7 would equal ?5.

Let A = 7-x.

Let B = x-7.

Does A = B for any x ?
