15-4x=2(3x+1)

15-4x=6x+1

-4x+6x+1-15

2x-14

x=-14/2=-7

**Quidditch**, Thursday, May 22, 2008 at 1:56pm15-4x = 2(3x+1)

15-4x = 6x + 2

Combine all the 'x' terms on one side and the constant terms on the other side.

15 - 2 = 6x + 4x

13 = 10x

So, x=?

Second line, on the right should be +2

Third line. What happened to equal signs? THis is awfully sloppy work.

15-4x=6x+2

subtract 15 from both sides.

Subtract 6x from both sides.
