-x+2/9y=1
\n" ); document.write( "9x+3y=6
\n" ); document.write( "Work on -x+2/9y=1 first
\n" ); document.write( "multiply each side by 9
\n" ); document.write( "-9x + 2y = 9
\n" ); document.write( "Now we have the two equations
\n" ); document.write( "-9x + 2y = 9 and
\n" ); document.write( "9x + 3y = 6
\n" ); document.write( "Add the two together
\n" ); document.write( "5y = 15
\n" ); document.write( "divide each side by 5
\n" ); document.write( "y = 3
\n" ); document.write( "Substitute 3 for y in 9x+3y=6
\n" ); document.write( "9x+3(3) = 6
\n" ); document.write( "9x + 9 = 6
\n" ); document.write( "add -9 to each side
\n" ); document.write( "9x = -3
\n" ); document.write( "divide each side by 9
\n" ); document.write( "x = -3/9 = -1/3
\n" ); document.write( "So we have y = 3 and x = -1/3\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
