Question

x-2/3+2×=5×2
x-2 por 3 +2× =5×por 2​

Answer 1

$\frac{x - 2}{3 + 2x} = \frac{5x}{2} \\ 2 x - 4 = 15x + 10 {x}^{2} \\ 10 {x}^{2} + 13x + 4 = 0 \\ x = \frac{ - 13 + - \sqrt{169 - 160} }{2 \times 10} \\ x = \frac{ - 13 + - 3}{20} \\ x_{1} = - \frac{1}{2} \\ x_{2} = - \frac{4}{5} \\ s = ( - \frac{4}{5} \: e \: - \frac{1}{2}$
