[tex]74.2 \div x = 14[/tex]

[tex]74 \frac{2}{10} \div x = 14 \\ \frac{371}{5} \div \frac{x}{1} = 14 \\ \frac{371}{5} \times \frac{1}{x} = 14 \\ \frac{371}{5x} = 14[/tex]

[tex]371 = 14 \times 5x \\ 371 = 70x[/tex]

[tex]x = \frac{371}{70} = \frac{53}{10} [/tex]

[tex]x = \frac{53}{10} = 5 \frac{3}{10} [/tex]
