Start off by cross multiplying to get
6(x-4) = 3*4
6x-24 = 12
what's next?
OpenStudy (anonymous):
I'm really bad with algebra. I'm not sure what it is your wanting me to multiply.
jimthompson5910 (jim_thompson5910):
we want to isolate x
so we want x all by itself
jimthompson5910 (jim_thompson5910):
how do we do this
OpenStudy (anonymous):
So I'd subtract all the numbers around it ??

kinda
more like add 24 to both sides (to undo the -24)
what do you get when you do this?
OpenStudy (anonymous):
By adding 2. If we add 24 tonegitive 24.... It would be zero
jimthompson5910 (jim_thompson5910):
no, we add 24 to both sides to get
6x-24 = 12
6x-24+24 = 12+24
6x = 36
what's next?
OpenStudy (anonymous):
Subtracting by the left side?
OpenStudy (anonymous):
I meant right side.

how do you undo multiplication?
OpenStudy (anonymous):
Division.
jimthompson5910 (jim_thompson5910):
so you divide both sides by 6
jimthompson5910 (jim_thompson5910):
6x = 36
x = 36/6
x = 6
jimthompson5910 (jim_thompson5910):
x is finally isolated and all by itself, so you're done
