Answer 2

what do u get?

Answer 3

what do you mean by everything?

Answer 4

every term:

Answer 5

simplify that

Answer 6

Come on it's just some multiplication.

Answer 7

so i just do 1/2 * 2, 2*2 & 4*2 ??

Answer 8

yes what do those numbers equal to?

Answer 9

yahya please don't give away the answer.

Answer 10

get free from w by multipling equation by w

Answer 11

You can't get rid of w. Do as I said, @renae_

Answer 12

1/2 * 2 = 1
2*2 = 4
4*2 = 8 ??

Answer 13

Yes that's what I wanted, but I wanted you to write it this way:
\[2*\frac{1}{2}*w + 2*2 = 2*4\]\[1*w+4=8\]\[w+4=8\]Now subtract 4 from both sides. What do you get?

Answer 14

1w + 4 =8
where do i subtract from?

Answer 15

Here:
w+4 - 4 = 8 - 4
Basically an equation is like a scale. Whatever you do to one side, you need to do to the other, to keep the scales balanced. So if you add 5 to one side, you have to add 5 to the other side as well. If you have to subtract 4 from one side, you have to subtract 4 from the other side as well.

Answer 16

w + 0 = 4? so B?

Answer 17

yes
