Need help with solving (x+2)/(4)-(x-1)/(3)=x-10

So here's my problem:

x+2/4 - x-1/3 =x-10

Do I start by multiplying both of the left fractions to get a common denominator of 12?

I have- 3x+6-4x-4 /12 =x-10

Then I simplify to get -x+2/12=x-10

Then I am stuck. I thought I should multiply by 12 to get rid of the fraction- -x+2=12x-120

I try to simplify from there, but the answer I get isn't right. What step am I going wrong??

Thanks!!

the step above should be ...
(3x + 6 - 4x + 4)/12 = x - 10
... do you see why?
