Question 729748


1)  solve for X:  

{{{a/bx-c=0}}}  

{{{a/bx=c}}}

{{{a=cbx}}}

{{{a/cb=x}}}........answer



2)  {{{(3x+1)/(x^2-9) - (2x-2)/(x^2 -9)}}}...if denominator same, just subtract numerators

{{{((3x+1) - (2x-2))/(x^2 -9)}}}


{{{(3x+1-2x+2)/(x^2 -9)}}}


{{{(x+3)/(x^2 -3^2)}}}.....factor denominator


{{{(x+3)/((x -3)(x+3))}}}


{{{cross((x+3))1/((x -3)cross((x+3)))}}}


{{{1/(x -3)}}}
