Thread: expand

I need help step by step if anyone has time thanks
-5(3x + 9 - 7y)



Thanks so much

What are you trying to find?

If its just multiply bracket by -5 then:

-5 * 3x = -15x
-5 * 9 = -45
-5 * -7y = 35y

-15x - 45 + 35y

what do you want to do? expand it?
if that is so...
-5(3x + 9 - 7y)

so what we do is multiply the -5 into 3x, 9 and -7y. Since it literally means -5 * (3x + 9 - 7y)

so it will become:
-15x - 45 + 35y

(-5 x 3x = -15x) (-5 x + 9 = -45) (-5 x -7y = 35y)

Thanks Geometor and r_maths!

-5 (3x + 9 - 7)
