Question

a student wrote the opposite of the expression(-4+x) as(x-4). what was his mistake? what is the correct answer?

Answer 1

If by `opposite` you mean `additive inverse`,
then the opposite of (-4+x) would be -(4+x)

Since addition is commutative, a+b = b+a
which is what is being illustrated in your example.

Answer 2

-4 + x = x + -4

Answer 3

Unless I'm misunderstanding what you meant by `opposite` +_+
Bahhh I dunno

Answer 4

thnx
