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( "
\n" );
