You can put this solution on YOUR website!
Solve the following systems by substitution:\r
\n" ); document.write( "\n" ); document.write( "L1) 4x - 12y = 5
\n" ); document.write( "L2) -x + 3y = -1
\n" ); document.write( "Solve L2) for x and substitute that in for x in L1):
\n" ); document.write( "-x+3y-3y=-1-3y
\n" ); document.write( "-x=-1-3y
\n" ); document.write( "-(-x)=-(-1-3y)
\n" ); document.write( "x=1+3y
\n" ); document.write( ":
\n" ); document.write( "4(1+3y)-12y=5
\n" ); document.write( "4+12y-12y=5
\n" ); document.write( "4+0=5
\n" ); document.write( "4=5
\n" ); document.write( "Your variables were eliminated and 4 does not = 5, there is no solution. These are parallel lines that will never intersect.
