Question 336549
{{{(x-3)/x=4/7}}} Start with the given equation.



{{{7(x-3)=4x}}} Cross multiply.



{{{7x-21=4x}}} Distribute.



{{{7x=4x+21}}} Add {{{21}}} to both sides.



{{{7x-4x=21}}} Subtract {{{4x}}} from both sides.



{{{3x=21}}} Combine like terms on the left side.



{{{x=(21)/(3)}}} Divide both sides by {{{3}}} to isolate {{{x}}}.



{{{x=7}}} Reduce.

Answer:


So the solution is {{{x=7}}}
