Starting with
\n" ); document.write( "x+3y= -2
\n" ); document.write( "-4x-5y=8
\n" ); document.write( "Multiply the first equation by 4
\n" ); document.write( "4(x+3y= -2)
\n" ); document.write( "4x+12y=-8
\n" ); document.write( "Add the second equation
\n" ); document.write( "4x + -4x + 12y + -5y = -8 + 8
\n" ); document.write( "7y = 0
\n" ); document.write( "y = 0
\n" ); document.write( "...
\n" ); document.write( "Multiply the first equation by 5 and the second equation by 3
\n" ); document.write( "5(x+3y= -2)
\n" ); document.write( "3(-4x-5y=8)
\n" ); document.write( "To get
\n" ); document.write( "5x+15y=-10
\n" ); document.write( "-12x-15y=24
\n" ); document.write( "Add the equations
\n" ); document.write( "5x + - 12x + 15y + -15y = -10 + 24
\n" ); document.write( "-7x = 14
\n" ); document.write( "x = -2
\n" ); document.write( "...
\n" ); document.write( "x = -2 and y = 0
