Did you notice that 4x+ 24= 4(x+ 6)? Do you see how that will help?

Your fourth line is incorrect. It should be:

28 + x = 3 * 4 * (x + 6)

And in the next to last line what happened to the "4(x+ 6)" that was in the denominator before?

I am assuming that the OP multiplied both sides by 4*(x+6).

I am assuming that the OP multiplied both sides by 4*(x+6).

Bit he didn't because the right side was still "3".

The OP doesn't show an understanding of multiplying both sides of the equation
by the LCD.
