You can put this solution on YOUR website!
x+2y =11
\n" ); document.write( "-x+5y=17\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Just add these equations together, and the x terms subtract out. Now you can solve for y:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7y=28
\n" ); document.write( "y=4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now substitute this value of y=4 back into either equation. The first equation will do:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x+2y=11
\n" ); document.write( "x+2(4)=11
\n" ); document.write( "x+8=11
\n" ); document.write( "x=3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check by substituting both numbers into the second equation:
\n" ); document.write( "-x+5y=17
\n" ); document.write( "-3+5(4)=17
\n" ); document.write( "-3+20=17\r
\n" ); document.write( "\n" ); document.write( "IT CHECKS!!\r
