From
\n" ); document.write( "-7x + 5y = -20
\n" ); document.write( "-3x - 2y = 8
\n" ); document.write( "let's multiply the top one by 2 and the bottom one by five...then add them...we get
\n" ); document.write( "-14x + 10y = -40
\n" ); document.write( "-15x - 10y = 40
\n" ); document.write( "now add them to get
\n" ); document.write( "-29x = 0 and
\n" ); document.write( "x = 0
\n" ); document.write( "then
\n" ); document.write( "y = -4
\n" ); document.write( "Solution is (0, -4)
\n" ); document.write( "
\n" );
