Answer 2

Solution :-

5x/3 - 4 = 2x/5

Taking LCM of the denominators and then solving it.

⇒ (5x - 12)/3 = 2x/5

Now cross multiplying.

⇒ 25x - 60 = 6x

⇒ 25x - 6x = 60

⇒ 19x = 60 

⇒ x = 60/19

⇒ Now, putting the value of x = 60/19 in 2x - 8

⇒ 2x - 8

⇒ (2*60)/19 - 8

⇒ 120/19 - 8

⇒ (120 - 152)/19

= - 32/19

So, the numerical value of 2x - 8 is - 32/19
