solve each system of equations by elimination\r
\n" ); document.write( "\n" ); document.write( "3x+5y = -1
\n" ); document.write( "2x-4y = 3
\n" ); document.write( "-----------------
\n" ); document.write( "Multiply thru the 1st equation by 2
\n" ); document.write( "Multiply thru the 2nd equation by 3
\n" ); document.write( "==================
\n" ); document.write( "6x + 10y = -2
\n" ); document.write( "6x - 12y = 9
\n" ); document.write( "------
\n" ); document.write( "Subtract and solve for \"y\":
\n" ); document.write( "22y = -11
\n" ); document.write( "y = -1/2
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"x\":
\n" ); document.write( "2x-4y = 3
\n" ); document.write( "2x -4(-1/2) = 9
\n" ); document.write( "2x + 2 = 9
\n" ); document.write( "2x = 7
\n" ); document.write( "x = 7/2
\n" ); document.write( "---------------
