Algebra.Com's Answer #32830 by pwac(253)![]() ![]() ![]() You can put this solution on YOUR website! Let x = smaller number \n" ); document.write( "So,larger number = x + 12 \n" ); document.write( "Need to sort out an equation from information given \n" ); document.write( "Smaller + twice the larger = 39. This gives us:\r \n" ); document.write( "\n" ); document.write( "x + 2(x+12)= 39. Multiply expression in brackets by 2 \n" ); document.write( "x + 2x + 24 = 39 Add x terms \n" ); document.write( "3x+24 = 39 Subtract 24 from both sides \n" ); document.write( "3x = 15 Divide both sides by 3 \n" ); document.write( "x = 5 This is your smaller number \n" ); document.write( "So, larger number is 5 + 12 = 17 \n" ); document.write( "Pete \n" ); document.write( " |
