Algebra.Com's Answer #346277 by jlshires(17)![]() ![]() ![]() You can put this solution on YOUR website! The key to solving this problem is that you know the integers are consecutive, even integers.\r \n" ); document.write( "\n" ); document.write( "The smallest you can set as x. therefore:\r \n" ); document.write( "\n" ); document.write( "Let the smallest integer = x \n" ); document.write( "Let the middle integer = x+2 \n" ); document.write( "Let the largest integer = x+4\r \n" ); document.write( "\n" ); document.write( "this will make them the consecutive even numbers. (ex: 2,4,6 or 8,10,12)\r \n" ); document.write( "\n" ); document.write( "The difference of the smallest integer and twice the largest integer is 10\r \n" ); document.write( "\n" ); document.write( "twice the largest would equal 2(x+4) Therefore:\r \n" ); document.write( "\n" ); document.write( "2(x+4)-x = 10 \n" ); document.write( "multiply out the 2\r \n" ); document.write( "\n" ); document.write( "2x+8-x=10\r \n" ); document.write( "\n" ); document.write( "combine like symbols (2x-x=x)\r \n" ); document.write( "\n" ); document.write( "x+8=10\r \n" ); document.write( "\n" ); document.write( "subtract 8 from both sides\r \n" ); document.write( "\n" ); document.write( "x=2\r \n" ); document.write( "\n" ); document.write( "Substitute x back into the original formulas\r \n" ); document.write( "\n" ); document.write( "x=2 \n" ); document.write( "x+2=4 \n" ); document.write( "x+4=6\r \n" ); document.write( "\n" ); document.write( "the numbers are 2, 4, 6\r \n" ); document.write( "\n" ); document.write( "(**Always put the numbers that you find back into the formula that you created to test your answer. ex: For this problem, but 2 and 6 back into the formula for \"the difference between the smallest and two times the largest equals 10. \r \n" ); document.write( "\n" ); document.write( "this would be (2*6)-2 = 12-2 = 10) \n" ); document.write( " |
