Algebra.Com's Answer #368868 by mathsmiles(68)![]() ![]() You can put this solution on YOUR website! Let's let X be the first (smallest) of these integers. Then the next consecutive integer is (X+1), the next is (X+2). \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "We are told the sum of these 3 is -15 so \n" ); document.write( "(X) + (X+1) + (X+2) = -15 Start solving!: \n" ); document.write( "X + X + 1 + X + 2 = -15 combining like terms: \n" ); document.write( "3X + 3 = -15 subtract 3 from each side \n" ); document.write( "3X = -18 divide by 3 on each side \n" ); document.write( "X = -6\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The 3 numbers are -6, -5, -4.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Checking: \n" ); document.write( " -6 + -5 + -4 = -15? \n" ); document.write( "-15 = -15 Correct! \n" ); document.write( " \n" ); document.write( " |
