Question 177088


{{{(1/3)s+7/9=(4/3)s}}} Start with the given equation.



{{{9((1/cross(3))s+7/cross(9))=9((4/cross(3))s)}}} Multiply both sides by the LCD {{{9}}} to clear any fractions.



{{{3s+7=12s}}} Distribute and multiply.



{{{3s=12s-7}}} Subtract {{{7}}} from both sides.



{{{3s-12s=-7}}} Subtract {{{12s}}} from both sides.



{{{-9s=-7}}} Combine like terms on the left side.



{{{s=(-7)/(-9)}}} Divide both sides by {{{-9}}} to isolate {{{s}}}.



{{{s=7/9}}} Reduce.

Answer:


So the answer is {{{s=7/9}}} which approximates to {{{s=0.778}}}.
