set them equal to each other and solve for x
\n" ); document.write( "4x+1=6x-4
\n" ); document.write( "5=2x
\n" ); document.write( "2.5=x
\n" ); document.write( "now substitute 2.5 for x in either equation
\n" ); document.write( "y=4*2.5+1
\n" ); document.write( "y=11
\n" ); document.write( "(2.5,11)
\n" ); document.write( "
