Question 117201

{{{x/10=9/30}}} Start with the given equation



{{{x=(9/30)*10}}} Multiply both sides by 10



{{{x=90/30}}} Multiply



{{{x=3}}} Simplify




So our answer is  {{{x=3}}} 



So you are correct, but I'm not sure where you got the step "0=0". As always, you can check this by plugging the solution back into the original equation


--------------------------------------

Check:


{{{x/10=9/30}}} Start with the given equation



{{{3/10=9/30}}} Plug in x=3



{{{3/10=3/10}}} Reduce the right side. Since the two sides of the equation are equal, this verifies our answer.
