You can put this solution on YOUR website!
Without parenthesese we don't know where your fractions begin and end. If I am misinterpretting this let me know:
\n" ); document.write( "L1) \"x-%285%2F3%29y=7\"
\n" ); document.write( "L2) \"%284%2F7%29x%2By=-13%2F7\"
\n" ); document.write( "Multiply L1 by 3 and L2 by 7 to clear the fractions.
\n" ); document.write( "L1)\"3%28x-%285%2F3%29y%29=3%287%29\" -->> \"3x-5y=21\"
\n" ); document.write( "L2)\"7%28%284%2F7%29x%2By%29=7%28-13%2F7%29\"-->> \"4x%2B7y=-13\"
\n" ); document.write( "Now multiply L1 by 4 and L2 by -3, add L1+L2 to eliminate the x's and solve for y:
\n" ); document.write( "L1) \"4%283x-5y%29=4%2821%29\" --> \"12x-20y=84\"
\n" ); document.write( "L2) \"-3%284x%2B7y%29=-3%28-13%29\"--> \"-12x-21y=39\"
\n" ); document.write( ":
\n" ); document.write( "12x-20y=84
\n" ); document.write( "-12x-21y=39
\n" ); document.write( "____________
\n" ); document.write( "-41y=123
\n" ); document.write( "\"-41y%2F-41=123%2F-41\"
\n" ); document.write( "\"y=-3\"
\n" ); document.write( "Substitute -41/14 in for y in one of the equations and solve for x.
\n" ); document.write( "\"x-%285%2F3%29%28-3%29=7\"
\n" ); document.write( "\"x%2B5=7\"
\n" ); document.write( "\"x%2B5-5=7-5\"
\n" ); document.write( "\"x=2\"
\n" ); document.write( "(x,y)=(2,-3)
\n" ); document.write( "Happy Calculating!!!\r
