You can put this solution on YOUR website!
y = 2x + 6
\n" ); document.write( "5x + 3y = 7\r
\n" ); document.write( "\n" ); document.write( "Substitute first equation into the second to find x:
\n" ); document.write( "5x + 3(2x + 6) = 7
\n" ); document.write( "5x + 6x + 18 = 7
\n" ); document.write( "11x = -11
\n" ); document.write( "x = -1\r
\n" ); document.write( "\n" ); document.write( "Substitute x back into first equation to find y:
\n" ); document.write( "y = 2x + 6
\n" ); document.write( "y = 2(-1) +6
\n" ); document.write( "y = -2 + 6
\n" ); document.write( "y = 4
\n" ); document.write( "Final Answer:
\n" ); document.write( "x = -1
\n" ); document.write( "y = 4 \n" ); document.write( "

\n" );
