Algebra.Com's Answer #77911 by Annabelle1(69)![]() ![]() ![]() You can put this solution on YOUR website! let you integers be x, x+1, x+2 \n" ); document.write( "three times the second is 3(x+1) minus the third -(x+2)=12 more than the first (x+1)+12\r \n" ); document.write( "\n" ); document.write( "so 3(x+1)-(x+2)=(x+1)+12 \n" ); document.write( "3x+3-x-2=x+1+12 \n" ); document.write( "2x+3=x+13\r \n" ); document.write( "\n" ); document.write( "minus x from both sides \n" ); document.write( "2x-x+3=x-x+13 \n" ); document.write( "x+3=13\r \n" ); document.write( "\n" ); document.write( "minus 3 from both sides \n" ); document.write( "x+3-3=13-3 \n" ); document.write( "x=10\r \n" ); document.write( "\n" ); document.write( "the first integer is 10 so teh second and third (x+1) and (x+2) are 11 and 12 \n" ); document.write( " |
