the sum of a number and three is less than nineteen less than the number.
\n" ); document.write( "it says define a variable, write an equality, and solve.
\n" ); document.write( "the statement is not an equality.
\n" ); document.write( "it is an inequality.
\n" ); document.write( "the statement, as far as i can tell states:
\n" ); document.write( "x + 3 < (x-19) - 19
\n" ); document.write( "when you simplify this equation, you get:
\n" ); document.write( "x + 3 < x - 38
\n" ); document.write( "you normally solve for x as follows:
\n" ); document.write( "subtract 3 from both sides of the equation to get:
\n" ); document.write( "x < x - 41
\n" ); document.write( "subtract x from both sides of the equation to get:
\n" ); document.write( "0 < -41
\n" ); document.write( "the x variable disappears.
\n" ); document.write( "if the remaining statement was true, then x could have been any value and the statement would be true.
\n" ); document.write( "since the remaining statement is false, than there is no solution to this equation.\r
