The solution is

Explanation:

The given expression is

We need to multiply and simplify the expression.

Let us multiply each of term within the parenthesis.

Thus, we get,

Now, simplifying each term in the expression, we have,

Adding the like terms, we get,

Hence, the simplified expression is

Therefore, the solution is

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
