You can put this solution on YOUR website!
3x - 5 > 4x
\n" ); document.write( "x is the number
\n" ); document.write( "the difference of 3 times the number and 5 is equivalent to 3x - 5
\n" ); document.write( "more than the number times 4 is equivalent to > 4x + 5
\n" ); document.write( "the equation is 3x-5 > 4x
\n" ); document.write( "subtract 4x from both sides of the equaton to get 3x - 5 - 4x > 0
\n" ); document.write( "combine like terms to get -x - 5 > 0
\n" ); document.write( "add 5 to both sides of the equation to get -x > 5
\n" ); document.write( "multiply both sides of the equation by -1 to get x < -5
\n" ); document.write( "note that multiplying both sides of an inequality by a negative number reverses the inequality.
\n" ); document.write( "your solution should be x < -5
\n" ); document.write( "you need to substitute for x in your original equation to see if this solution is good.
\n" ); document.write( "your original equation is 3x - 5 > 4x.
\n" ); document.write( "pick a number for x < -5.
\n" ); document.write( "let's try -6.
\n" ); document.write( "your original equation is 3x - 5 > 4x
\n" ); document.write( "replace x with -6 to get 3(-6) - 5 > 4(-6)
\n" ); document.write( "simplify to get -18 - 5 > -24
\n" ); document.write( "combine like terms to get - 23 > -24 which is true.
\n" ); document.write( "this means your solution is good.
\n" ); document.write( "let's try a much larger difference to see it it's still true.
\n" ); document.write( "let's try x = -20
\n" ); document.write( "your original equation is 3x - 5 > 4x
\n" ); document.write( "replace x with -20 to get 3(-20) - 5 > 4(-20)
\n" ); document.write( "simplify to get -60 - 5 > -80
\n" ); document.write( "combine like terms to get -65 > -80
\n" ); document.write( "since -65 > -80 is a true statement, your solution is good.
\n" ); document.write( "
\n" ); document.write( "
\n" );
