Question 11660
Express all values as fractions. Then operate on the equation to eliminate the fraction associated with x.
However, 2/3x is ambiguous. Do you mean 2 divided by 3x or do you mean 2/3 times x?
Let's assume you mean {{{(2/3)x}}}
In this case the fraction is {{{2x/3}}}
This makes the equation 
{{{2x/3=12/7}}}
{{{2x = 36/7}}} [multiplying both sides by 3]
{{{x = 18/7}}} [dividing both sides by 2], or x = 2 4/7
If you mean {{{2/3x}}} then the equation is 
{{{2/3x=12/7}}}
{{{2 = 36x/7}}} [multiplying both sides by 3x]
{{{14=36x}}} [multiplying both sides by 7]
{{{14/36=x}}} [dividing both sides by 36], or x = 7/18
