Step-by-step explanation:

[tex]1. \: 3(50) = 5n[/tex]

[tex]150 = 5n[/tex]

[tex] \frac{150}{5} = \frac{5n}{5} [/tex]

[tex]n = 30[/tex]

[tex]2. \: 64(9) = 8n[/tex]

[tex]576 = 8n[/tex]

[tex] \frac{576}{8} = \frac{8n}{8} [/tex]

[tex]n = 72[/tex]

[tex]3. \: 2(81) = 9n[/tex]

[tex]162 = 9n[/tex]

[tex] \frac{162}{9} = \frac{9n}{9} [/tex]

[tex]n = 18[/tex]

[tex]4. \: 5n = 12(35)[/tex]

[tex]5n = 420[/tex]

[tex] \frac{5n}{5} = \frac{420}{5} [/tex]

[tex]n = 84[/tex]

[tex]5. \: 2(18) = 4n[/tex]

[tex]36 = 4n[/tex]

[tex] \frac{36}{4} = \frac{4n}{4} [/tex]

[tex]n = 9[/tex]
