\n" ); document.write( "\n" ); document.write( " $\"y=2-3x\"$
\n" ); document.write( " $\"6x%2B2y=7\"$
\n" ); document.write( "--------------------since first equation is already solved for $\"y\"$ , use substitution method\r
\n" ); document.write( "\n" ); document.write( " $\"6x%2B2y=7\"$ ........substitute $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"6x%2B2%282-3x%29=7\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"6x%2B4-6x=7\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"4=7\"$ -> is false, therefore the system of equations has no solution \r
