3x-5y= 7
\n" ); document.write( "5x-2y=-1
\n" ); document.write( "------
\n" ); document.write( "Multiply the 1st equation by 2.
\n" ); document.write( "Multiply the 2nd equation by 5.
\n" ); document.write( "-----------------------
\n" ); document.write( "6x-10y = 14
\n" ); document.write( "25x-10y =-5
\n" ); document.write( "------
\n" ); document.write( "Subtract 1st from 2nd and solve for \"x\":
\n" ); document.write( "19x = -19
\n" ); document.write( "x = -1
\n" ); document.write( "---
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "5x-2y = -1
\n" ); document.write( "5(-1)-2y = -1
\n" ); document.write( "2y =-4
\n" ); document.write( "y = -2
\n" ); document.write( "---
