You can put this solution on YOUR website!
X equal 7 x-9
\n" ); document.write( "assume the problem is
\n" ); document.write( "x = 7x - 9
\n" ); document.write( "Add 9 to both sides
\n" ); document.write( "x + 9 = 7x
\n" ); document.write( "Subtract x from both sides
\n" ); document.write( "9 = 7x - x
\n" ); document.write( "9 = 6x
\n" ); document.write( "divide both sides by 6
\n" ); document.write( "9/6 = 1x
\n" ); document.write( "1.5 = x
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "see if that works in the original equation, replace x with 1.5
\n" ); document.write( "1.5 = 7(1.5) - 9
\n" ); document.write( "1.5 = 10.5 - 9
\n" ); document.write( "1.5 = 1.5; equality reigns, that is a good solution
\n" ); document.write( ":
\n" ); document.write( "perform math operations on both sides until you get x on one side by itself
\n" ); document.write( "that solves the problem. then check your answer in the original equation \n" ); document.write( "
\n" );
