You can put this solution on YOUR website!
$\"%28%28n-3%29%29%2F%28%286n-6%29%29\"$ = $\"1%2F9\"$ - $\"%28%28n-3%29%29%2F%28%284n-4%29%29\"$
\n" ); document.write( "We can do some factoring here
\n" ); document.write( " $\"%28%28n-3%29%29%2F%286%28n-1%29%29\"$ = $\"1%2F9\"$ - $\"%28%28n-3%29%29%2F%284%28n-1%29%29\"$
\n" ); document.write( "Right here we can answer the question about excluded values
\n" ); document.write( "You can see that n cannot = 1, as it would put zeros in the denominators
\n" ); document.write( ":
\n" ); document.write( "The common denominator would be 36(n-1), multiply equation by this
\n" ); document.write( "36(n-1)* $\"%28%28n-3%29%29%2F%286%28n-1%29%29\"$ = 36(n-1)* $\"1%2F9\"$ - 36(n-1)* $\"%28%28n-3%29%29%2F%284%28n-1%29%29\"$
\n" ); document.write( "Cancel the denominators and you have
\n" ); document.write( "6(n-3) = 4(n-1) - 9(n-3)
\n" ); document.write( "6n - 18 = 4n - 4 - 9n + 27
\n" ); document.write( "6n - 18 = -5n + 23
\n" ); document.write( "Combine n's on the left, numbers on the right
\n" ); document.write( "6n + 5n = 23 + 18
\n" ); document.write( "11n = 41
\n" ); document.write( "n = $\"41%2F11\"$
\n" ); document.write( "n ~ 3.73, kind of a nasty solution but it seems to check out. C \n" ); document.write( "
