Ok so an online math website for my class has this question :
D = (6H)/(H-12S) Solve for H.

How do you solve this?? I cant seem to get H by itself and as far as I get is H = 12S + 6H/D. I really need help its due tomorrow.

Click to expand...

H - 6*H/D = 12*S ............... collect all the 'H' terms on one side

H*(1 - 6/D) = 12*S.............. Factor out 'H'

Now continue....
 
Pay particular attention to that "factoring" bit. It's a trick that many students miss, or forget on the test. And you should expect a "factoring" quesetion on the next test! ;)
