Algebra.Com's Answer #48295 by adamchapman(301)![]() ![]() ![]() You can put this solution on YOUR website! let the first number be called \"a\", and the second \"b\".\r \n" ); document.write( "\n" ); document.write( "from the question, we can tell that a-b=20............. eqn 1 \r \n" ); document.write( "\n" ); document.write( "also from the question,\r \n" ); document.write( "\n" ); document.write( "b goes into a 2 times, with 5 left over. This tells us: 2b+5=a.......... eqn 2\r \n" ); document.write( "\n" ); document.write( "Now if we replace a in the first equation withe equation 2, we get\r \n" ); document.write( "\n" ); document.write( "2b+5-b=20 \n" ); document.write( "and rearranging: \n" ); document.write( "b+5=20 \n" ); document.write( "b=15\r \n" ); document.write( "\n" ); document.write( "Now we can replace the b in equation 2 with the number 15: \n" ); document.write( "2(15)+5=1 \n" ); document.write( "30+5=a \n" ); document.write( "a=35 \n" ); document.write( " |
