Algebra.Com's Answer #195219 by roseo(33)![]() ![]() ![]() You can put this solution on YOUR website! Let x= the first even integer \n" ); document.write( "x+2 = the second even integer \n" ); document.write( "x+4 = the third even integer (Because we know to get the next even integer we just add 2) \n" ); document.write( "Then the sum of the first two would be x+x+2 and the sum of the third and -10 would be x+4+(-10) or x-6 . \n" ); document.write( "Therefore we can write the equation \n" ); document.write( "x+x+2 = x-6 \n" ); document.write( "Combining like terms on the left we have \n" ); document.write( "2x+2 = x-6 \n" ); document.write( "Then subtract x from each side \n" ); document.write( "x+2 = -6 \n" ); document.write( "Then subtract 2 from each side so we have \n" ); document.write( "x=-8 \n" ); document.write( "Then x+2 = -8+2 or -6 \n" ); document.write( "and x+4 = -8+4 or -4. \n" ); document.write( "So your three consecutive integers are -8,-6, and-4 \n" ); document.write( " |
