You can put this solution on YOUR website!
let the two consecutive even integers be equal to x and x + 2.
\n" ); document.write( "your equation becomes 5x <= 4 * (x + 2)
\n" ); document.write( "simplify to get:
\n" ); document.write( "5x <= 4x + 8
\n" ); document.write( "solve for x to get:
\n" ); document.write( "x <= 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this means that x has to be either:
\n" ); document.write( "8 or 6 or 4 or 2 or 0 or -2 or -4 .....\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this also means that x cannot be greater than 8, which means that x cannot be either:
\n" ); document.write( "10 or 12 or 12 or 16 or 18 .........\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when x = 8, the equation becomes 5 * 8 <= 4 * 10 which becomes 40 <= 40 which is true.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when x = 6, which is smaller than 8, the equation becomes 5 * 6 <= 4 * 8 which becomes 30 <= 32 which is true.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when x = 10, which is greater than 8, the equation becomes 5 * 10 <= 4 * 12 which becomes 50 <= 48 which is false.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can graph this by breaking it up into two equations as listed below.
\n" ); document.write( "y = 5 * x
\n" ); document.write( "y = 4 * (x + 2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you graph both these equations on the same graph as shown below.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"$$$\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the red line is the graph of the equation y = 5x.
\n" ); document.write( "the blue line is the graph of the equation y = 4 * (x + 2).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can see that the red line is below the blue line up until the value of x is equal to 8, after which it is above the blue line.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this visually confirms the fact that 5x <= 4 * (x + 2) when the value of x is less than or equal to 8.\r
