Evaluate the following expression given the function.
function: h(x)=12/x
problem: h(x) = 2
solution: 2 = 12/x.
1/12 * 2 = 12/x *1/12 (mulitply both sides by 1/12 to get x by itself.
2/12 = 1/x
1/6 = 1/x (simplified 2/12)
I don't think this is right. Can you explain how to get the 'x' out of the denominator?

don't be scared by that x. It's juts a denominator. To get rid of it, multiply both sides by x.
Now, to find x when h = 2, just do what you did:
12/x = 2
now just multiply by x:
12 = 2x
x = 6posted by Steve

Thanks! That was so much easier :).
