College prealgebra. You subtract 5 from both sides. That will leave you with 16/3x=5/95/9. Right? Because you need a denominator that's the same in order to subtract. So you're left with 16/3x=9. Now you need the x alone. So the opposite of multiplication is division. And then I get lost here. I'm sure I did something wrong earlier. I'm only on question 17 of 66 and I've been through four pieces of papers trying to figure this problem out.

5+16/3x=5/9 Pulling my hair out over this. Help, please. Relax 16/3x = (16/3)x = 16x / 3 : that's same thing, but clearer 5 + 16x / 3 = 5/9 Multiply through by 9: 45 + 48x = 5 ; still with me? Subtract 45 from each side: 48x = 40 Divide each side by 48: x = 40/48 Simplify: x = 5/6 Don't give up...like anything else, practice required...
