Question 369988
{{{5/6=(7n+9)/9}}} Start with the given equation.



{{{5*9=6(7n+9)}}} Cross multiply



{{{45=6(7n+9)}}} Multiply



{{{45=42n+54}}} Distribute.



{{{0=42n+54-45}}} Subtract {{{45}}} from both sides.



{{{-42n=54-45}}} Subtract {{{42n}}} from both sides.



{{{-42n=9}}} Combine like terms on the right side.



{{{n=(9)/(-42)}}} Divide both sides by {{{-42}}} to isolate {{{n}}}.



{{{n=-3/14}}} Reduce.

Answer:


So the solution is {{{n=-3/14}}}
