SOLUTION: Hi there, i need some help with this question:
twice a number is 60 times more than 5 times the number - what is the number?
I believe the formula should equate to:
2x = 6
Question 667159: Hi there, i need some help with this question:
twice a number is 60 times more than 5 times the number - what is the number?
I believe the formula should equate to:
2x = 60.(5x)
but that doesn't make any sense.
Or if it's written as: 2y = 60.(5x), then potential solutions could be: y=150, x =1
not entirely sure which is correct.
cheers,

You can put this solution on YOUR website! Your first equation is correct. Just follow through
What number times itself is equal to itself? only zero.
Do not make the mistake of saying
Why is dividing both sides above by x a mistake?? That is all good EXCEPT if x = 0, in which case the resulting x/x is undefined. Watch out for this type of thing. It happens more often then you think. If you get a strange answer .. and the algebra looks just fine ... make sure you don't have a division by zero lurking in there somewhere.
