Question

Hi, I'm in 7th grade and I'm about to fail Mathematics. Please help me...
2x - 5x =

Answer 1

-3x

Explanation:

The order of where the terms are placed definitely matter for subtraction. 5x-2x is 3x, but because the smaller number is first, we've gone into the negatives. Think of it like this:

2x - 5x

-2x -2x

__ __

0 -3x

Because we still have the - in front of the 3, it is a negative 3.

Hope this helps!

Answer 2

i beliebe 3×=0

ao the answer should be x/0
