When variables are on both sides, you should move the ______ value variable by using the inverse operation.

Answer explanation

You will move the smaller value variable (-6x) to the side of the larger value (-4x) variable by using the inverse operation (+6x).

Remember, a negative number may be larger, but actually be the smaller VALUE.

For example:

6 is greater than 4 BUT

-6 is less than -4
