solve the equation
- math(is this how you work this) - Quidditch, Thursday, May 22, 2008 at 1:56pm
15-4x = 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

No, you made a handfull of errors.
Second line, on the right should be +2
Third line. What happened to equal signs? THis is awfully sloppy work.
subtract 15 from both sides.
Subtract 6x from both sides.
