{{{(5/7)x+1/7=3}}} Start with the given equation.



{{{7((5/cross(7))x+1/cross(7))=7(3)}}} Multiply both sides by the LCD {{{7}}} to clear any fractions.



{{{5x+1=21}}} Distribute and multiply.



{{{5x=21-1}}} Subtract {{{1}}} from both sides.



{{{5x=20}}} Combine like terms on the right side.



{{{x=(20)/(5)}}} Divide both sides by {{{5}}} to isolate {{{x}}}.



{{{x=4}}} Reduce.

Answer:


So the solution is {{{x=4}}}
