Algebra.Com's Answer #121824 by Mathtut(3670)![]() ![]() ![]() You can put this solution on YOUR website! call the numbers a and b. a+b=50 so a=50-b (3 times a)(3a)=5+(2 times b)(2b)\r \n" ); document.write( "\n" ); document.write( "re written as 3a=5+2b. Now substituting a's value from first equation into 2nd equation we get 3(50-b)= 5+2b or 150-3b=5+2b adding 3b and subtracting 5 from each side we get 5b=145 so b =29 so since a=50-b(29) the a =21\r \n" ); document.write( "\n" ); document.write( "answer: a=21 and b=29 \n" ); document.write( " |
