Question

which of the following equations are true?
1) -x +0+(- x) = 0
2) -x-(-x) =0
3) none of the above

Answer 1

do u have any idea?

Answer 2

1.) The +0+ doesn't have any value, so the equation simplifies to -x - x = 0, and when you combine the two -x's you get -2x = 0.

2.) -x - (-x) is the same thing as -x + x, so the equation simplifies to -x + x = 0. Since the positive x and the negative x cancel each other out, the equation becomes 0 = 0.

So now we're left with:
1.) -2x = 0
2.) 0 = 0

I'll let you figure out which one is true ;)

Answer 3

#2 is the correct answer
