-3x+21

Step-by-step explanation:

Using distributive property

(-3*x)-(-3*7)

-3x-(-21)

-3x+21

Answer 2

Answer:

x=23

Step-by-step explanation:

You have to multiply -3 to both the x and -7.

that is how you get -3x + 21. (because -3 time -7 = Positive 21.)

then you want to get x by itself which then you would add 3 to both sides giving you X=23.
