Answer:
x = 15
x = 4
Step-by-step explanation:
Let ( 2 x / ( x - 5 ) ) be a
a² + 5 a - 24 = 0
⇒ a² + 8 a - 3 a - 24 = 0
⇒ a ( a + 8 ) - 3 ( a + 8 ) = 0
⇒ ( a - 3 )( a + 8 ) = 0
⇒ a = 3
⇒ a = - 8
Either :
2 x / ( x - 5 ) = 3
⇒ 2 x = 3 x - 15
⇒ x = 15
Or :
2 x / ( x - 5 ) = - 8
⇒ 2 x = 40 - 8 x
⇒ 10 x = 40
⇒ x = 4
