I see you've answered Alan, but I had to post this because I put like 10 minutes into this LaTeX. :)

 

12(x651)+5(x5+41)+10=6(x1351)Distribute the 12, 5, and 6 into their parentheses(12×x6)(12×51)+(5×x5)+(5×41)+10=(6×x1)(6×351)(12x6)(601)+(5x5)+(201)+10=6x12101(2x1)(601)+(x1)+(201)+10=6x121012x60+x+20+10=6x2103x60+20+10=6x2103x30=6x21030=3x210180=3x60=xx=60

Multiplying through to get rid of the brackets this becomes:

2x - 60 + x + 20 + 10 = 6x - 210

or:  3x - 30 = 6x - 210

Add 210 to both sides:

3x + 180 = 6x

Subtract 3x from both sides:

180 = 3x

Divide both sides by 3:

x = 60

That's true. It's always good to have a few consistent answers.

You did all of that in ten minutes?

That is much more impressive than solving the equation!
