[tex] \frac{3}{8} = \frac{75}{100} + \frac{27}{1} \div \frac{4}{x + 1} \\ \frac{3}{8 } = simplifici \: cu \: 25 \: \frac{3}{4} + \frac{27}{1} \times \frac{x + 1}{4 } \\ \frac{3}{8} = \frac{3}{4} + \frac{27(x + 1)}{4} \\ \frac{3}{8} = \frac{3}{4} + \frac{27x + 27}{4 } \\ amplifici \: cu \: 2 \\ 3 = 6 + 54x + 54 \\ 3 = 60 + 54x \\ 60 + 54x = 3 \\ 54x = - 57 \\ x = - \frac{ 57}{54} [/tex]
sper sa fie bun
