Perhatikan gambar berikut. Tentukan nilai x

[tex] \frac{3}{x} = \frac{6}{(6 + 4)} [/tex]
[tex] \frac{3}{x} = \frac{6}{10} [/tex]
[tex]3 \times 10 = 6x[/tex]
[tex]30 = 6x[/tex]
[tex]6x = 30[/tex]
[tex]x = \frac{30}{6} [/tex]

[tex]x = 5cm[/tex]

3/x = 6/6+4

3/x = 6/10

6x = 3 dikali 10

6x = 30

x = 30/6 = 5
