You can put this solution on YOUR website!
2x + 5y = 10
\n" ); document.write( "5x - 2y = 10
\n" ); document.write( "----->Add 2/5 the first equation to the second.
\n" ); document.write( "2x + 5y = 10
\n" ); document.write( "(29/5)x = 14 implies x=70/29\r
\n" ); document.write( "\n" ); document.write( "Now put that value for x into the first equation.
\n" ); document.write( "2(70/29)+5y=10
\n" ); document.write( "140/29+5y=10
\n" ); document.write( "5y=150/29 implies y=150/145=30/29\r
\n" ); document.write( "\n" ); document.write( "giving solution set (70/29,30/29). Check that on your own by plugging the values into both equations.
