Question 667159
Your first equation is correct. Just follow through
{{{2x = 60 * 5x}}}
{{{2x = 300x}}}
{{{x= 150x}}}
What number times itself is equal to itself? only zero.

Do not make the mistake of saying
{{{x = 150x}}}
{{{x/x = 150}}}
{{{1 = 150}}}
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.
