You can put this solution on YOUR website!
An integer is just a counting number, but it can
\n" ); document.write( "be + or -
\n" ); document.write( "Let the integers be $\"+a+\"$ and $\"+b+\"$
\n" ); document.write( "given:
\n" ); document.write( "(1) $\"+a+=+2b+-+4+\"$
\n" ); document.write( "(2) $\"+a%2Ab+=+70+\"$
\n" ); document.write( "-------------------
\n" ); document.write( "Substitute (1) into (2)
\n" ); document.write( "(2) $\"+%28+2b+-+4+%29%2Ab+=+70+\"$
\n" ); document.write( "(2) $\"+2b%5E2+-+4b+=+70+\"$
\n" ); document.write( "(2) $\"+b%5E2+-+2b+=+35+\"$
\n" ); document.write( "(2) $\"+b%5E2+-+2b+-+35+=+0+\"$
\n" ); document.write( "(2) $\"+%28+b+%2B+5+%29%2A%28+b+-+7+%29+=+0+\"$ ( by looking at it )
\n" ); document.write( " $\"+b+=+7+\"$
\n" ); document.write( "Now find $\"+a+\"$
\n" ); document.write( "(2) $\"+a%2Ab+=+70+\"$
\n" ); document.write( "(2) $\"+a+=+70%2Fb+\"$
\n" ); document.write( "(2) $\"+a+=+70%2F7+\"$
\n" ); document.write( "(2) $\"+a+=+10+\"$
\n" ); document.write( "------------------
\n" ); document.write( "7 and 10 are solutions
\n" ); document.write( "check:
\n" ); document.write( "(1) $\"+a+=+2b+-+4+\"$
\n" ); document.write( "(1) $\"+10+=+2%2A7+-+4+\"$
\n" ); document.write( "(1) $\"+10+=+10+\"$
\n" ); document.write( "OK
\n" ); document.write( "Note that $\"+b+=+-5+\"$ will also work. Just find
\n" ); document.write( " $\"+a+\"$ the same way, and you have another solution
\n" ); document.write( "Hope this helps
\n" ); document.write( " \n" ); document.write( "

\n" );
