Algebra.Com's Answer #122181 by Mathtut(3670)![]() ![]() ![]() You can put this solution on YOUR website! lets call the smaller a and the larger b\r \n" ); document.write( "\n" ); document.write( "b=2a-5 a+b=28 solve for a in the 2nd equation and we get a=28-b. now take the value of a and substitute it into the 1st equation. b=2(28-b)-5 now distribute the right side \n" ); document.write( "b=56-2b-5 combine terms \n" ); document.write( "b=51-2b add 2b to each side \n" ); document.write( "3b=51 divide by 3 \n" ); document.write( "b=17 and since a=28-b(17) then a =11\r \n" ); document.write( "\n" ); document.write( "so the smaller number is 11 and the larger is 17 \n" ); document.write( " \n" ); document.write( " |
