Question

Like terms to 5x


(help!!)

Answer 1

Select these:

x

-x

40x

-30x

In all of these terms, a number is being multiplying by x (and x only) just like in the question! That's how to tell.

For the "x" option, remember that an x alone equates to 1x. So, 1 is being multiplied by x.

For the "-x" option, remember that an -x alone equates to -1x. So, -1 is being multiplied by x.
