Question

Solve the following question​

Answer 1

Step-by-step explanation:

cross multiplication

9x=4(x+15)

9x=4x+ 60

9x-4x= 60

5x=60

x= 60/5

x= 12

Answer 2

Answer:

$\frac{x}{x + 15 } = \frac{4}{9}$

$\frac{x}{15x} = \frac{4}{9}$

$15x = 2.25$

$x = \frac{2.25}{15}$

$x = 0.15$

is your right answer
