You can put this solution on YOUR website!
Plug the second equation into the first equation:
\n" ); document.write( "3y+(2y-1)=4
\n" ); document.write( "5y-1=4
\n" ); document.write( "5y=5
\n" ); document.write( "y=1\r
\n" ); document.write( "\n" ); document.write( "Now plug your answer into the second equarion:
\n" ); document.write( "x=2(1)-1
\n" ); document.write( "x=2-1
\n" ); document.write( "X=1\r
\n" ); document.write( "\n" ); document.write( "To check your work plug both answers into the same equation:
\n" ); document.write( "3(1)+(1)=4
\n" ); document.write( "3+1=4
\n" ); document.write( "4=4
\n" ); document.write( "
\n" ); document.write( "
\n" );
