-3 x + 4 y = -19.5 .............1
\n" ); document.write( "-3 x + 1 y = -10.5 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by -4
\n" ); document.write( "-3 x 4 y = -19.5
\n" ); document.write( "12 x -4 y = 42
\n" ); document.write( "Add the two equations
\n" ); document.write( "9 x = 22.5
\n" ); document.write( "/ 9
\n" ); document.write( "x = 2.50 OR 2 1/ 2
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "-3 x + 4 y = -19.5
\n" ); document.write( "-7.5 + 4 y = -19.5
\n" ); document.write( " 4 y = -19.5 + 7.5
\n" ); document.write( " 4 y = -12
\n" ); document.write( " y = -3\r
\n" ); document.write( "\n" ); document.write( "(5/2,-3)
