<PRE><B>Question 550328</B>
{{{c+7/4=6/7}}} Start with the given equation.



{{{28(c+7/cross(4))=28(6/cross(7))}}} Multiply both sides by the LCD {{{28}}} to clear any fractions.



{{{28c+49=24}}} Distribute and multiply.



{{{28c=24-49}}} Subtract {{{49}}} from both sides.



{{{28c=-25}}} Combine like terms on the right side.



{{{c=(-25)/(28)}}} Divide both sides by {{{28}}} to isolate {{{c}}}.

Answer:


So the solution is {{{c=-25/28}}} </PRE>
