How does -2x + x equal -x ?
shepuryov [24]

Answer:

See below.

Step-by-step explanation:

-2x+x=-x

because we combine like terms. You will essentially ignore the x and just do -2 + 1, which is -1. So, the answer would be -1x which is simply just -x.

To see why we can combine like terms, use the distributive property. So we have:

-2x+x

This is the same thing as saying:

=(-2)x+(1)x

Factor out the x:

=x(-2+1)

Add:

=x(-1)

And simplify:

=-1x\\=-x
