Question 600630: 12/x=4 I understand the golden rule in this situation is to do the opposite. The opposite of division would be multiplication. I can figure out the answer when the variable is the numerator, but I get confused when the variable is the denominator. I know that x=3, but I need help on showing step by step how I got there. If y/6=2, times each side by 6, which would be 6y/6=2(6) or y=12. Going back to by problem it would be 144/x=48. I would appreciate it if someone could show me step by step when time allows. THANK YOU!!

12%2Fx+=+4 Start with the given equation


12+=+4x Multiply both sides by 'x'


12%2F4=x Divide both sides by 4


3=x Reduce


x=3 Flip the equation


So the answer is x=3

====================================================================

You are correct. The solution to y%2F6=2 is y=12. Nice job.

====================================================================

144%2Fx=48 Start with the given equation


144=48x Multiply both sides by x.


144%2F48=x Divide both sides by 48.


3=x Reduce.


x=3 Flip the equation.


So the answer is x=3
