52x−8−1=9
and x≠8

Start Fraction 5 over 2 x minus 8 End Fraction minus 1 equals 9 and x does not equal 8

52x−8−1=9
and x≠4

Start Fraction 5 over 2 x minus 8 End Fraction minus 1 equals 9 and x does not equal 4

52x−8−1=9
and x≠−4

Start Fraction 5 over 2 x minus 8 End Fraction minus 1 equals 9 and x does not equal negative 4

52x−8=9
and x≠−8

Start Fraction 5 over 2 x minus 8 End Fraction equals 9 and x does not equal negative 8

Answer 1

5/(2x − 8) − 1 = 9 and x ≠ 4

Reason: the denominator 2x − 8 cannot be 0, so 2x − 8 ≠ 0 → x ≠ 4.
