solve the following system of equations using substitution method:
\n" ); document.write( "y=x+4
\n" ); document.write( "Y=2X+3
\n" ); document.write( "-----------
\n" ); document.write( "Since they both equal y, they equal each other.
\n" ); document.write( "x+4 = 2x+3
\n" ); document.write( "Take it from there.
\n" ); document.write( "
\n" );
