You can put this solution on YOUR website!
start with z = (x-8)/2x
\n" ); document.write( "multiply both sides of the equation by 2x to get:
\n" ); document.write( "2xz = x-8
\n" ); document.write( "subtract x from both sides of the equation to get:
\n" ); document.write( "2xz - x = -8
\n" ); document.write( "factor out the x on the left side of the equation to get:
\n" ); document.write( "x * (2z-1) = -8
\n" ); document.write( "divide both sides of the equation by (2z-1) to get:
\n" ); document.write( "x = -8/(2z-1)
\n" ); document.write( "that's your solution.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "to confirm, take any random value for x and solve for z in z = (x-8)/(2x).
\n" ); document.write( "i used x = 3000.
\n" ); document.write( "you will get z = .4986666667.
\n" ); document.write( "now, take z = .4986666667 and solve for x in x = -8/(2z-1) to get z = 3000.
\n" ); document.write( "this confirms the equation for x is good.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your original equation was z = (x-8)/2x.
\n" ); document.write( "your solution is x = -8/(2z-1).\r
