Respuesta :

Given :

  • 45x[ 4/9 = 1/5 + 1/x ]

To Do :-

  • To multiply 45x to all the terms .

Solution :-

Given that ,

  • 45x[ 4/9 = 1/5 + 1/x ]

Distributive property of Multiplication over addition ,

  • a( b + c ) = ab + ac

So that ,

  • 45x * 4/9 = 45x* 1/5 + 45 x * 1/x
  • 5x * 4 = 9x + 45
  • 20x = 9x + 45

Step-by-step explanation:

As it says, multiply 45x to all the terms. This is required to get rid of fractions.

See the steps below:

  • 45x [ 4/9 = 1/5 + 1/x]
  • 45x(4/9) = 45x(1/5) + 45x(1/x)    ⇒ multiply
  • 5x(4) = 9x + 45                          ⇒ simplify
  • 20x = 9x + 45                            ⇒ end result without fractions
