Answer:
[tex]x = 7.2[/tex]
Step-by-step explanation:
[tex] \frac{16}{x} - 4 = \frac{4}{9} \\ \frac{16}{x} = \frac{4}{9} + 4 \\ \frac{16}{x} = \frac{4}{9} + \frac{4 \times 9}{1 \times 9} \\ \frac{16}{x} = \frac{4 + 36}{9} \\ \frac{16}{x} = \frac{40}{9} \\ use \: \: \: cross \: \: multipication \\ 16 \times 9 = 40x \\ \frac{16 \times 9}{40} = x \\ 7.2 = x[/tex]
