Question 713047
Add positive 3/11 to both sides of the equation, AND THEN multiply both sides by (x-11) and by 11.  


{{{(y-7)/(x-11)=-3/11}}}
{{{(y-7)/(x-11)+3/11=0}}}
{{{11*(x-11)((y-7)/(x-11))+11*(x-11)(3/11)=0}}}
{{{11(y-7)+3(x-11)=0}}}
{{{11y-77+3x-33=0}}}
3x+11y=77+33
{{{highlight(3x+11y=110)}}}
