Solve the 1st equation for \"y\": y=6x+4
\n" ); document.write( "Substitute into the 2nd equation, as follows;
\n" ); document.write( "X+2(6X+4)=7
\n" ); document.write( "X+12X+8=7
\n" ); document.write( "13X=-1
\n" ); document.write( "X=-1/13
\n" ); document.write( "Substitut that into y=6x+4
\n" ); document.write( "y=6(-1/13)+4
\n" ); document.write( "y=-6/13-52/13
\n" ); document.write( "y=46/13
\n" ); document.write( "Solution: x=-1/13; y=46/13
