HOW DO I DO:

Question

1/3(3x+9)=2x+3?

HOW DO I SOLVE IT?

Answer 1

1/3(3x+9)=2x+3

Distributive property: 1x + 3 = 2x + 3

1x = 2x

1x / 1 = 2x / 1

x = 2x

Now do you see it?

Answer 2

Thanks so much!

But why doesn't it work when I do:
1/3(3x+9)=2x+3
1x + 3 = 2x + 3
1x-2x=3-3
-x=0
????????????????

Answer 3

Your goal is to find x. To do so, you separate the constants from the variables. You cannot subtract 2x in this case, you need to divide.

Answer 4

um.... I think I get it now.
Thank you so much.

Answer 5

You're welcome.

Answer 6

actually, you can subtract the 2x. Your calculations are correct. It still comes out x=0

Answer 7

1/3(3x+9)=2x+3

x + 3 = 2x + 3
x-x + 3 = 2x -x + 3
3 = x +3
3-3 = x + 3 -3

x = 0
