Question

x+2/3 - x-2/5 = 2 + 3x -2/15

Answer 1

$x + \frac{2}{3} - x - \frac{2}{5} = 2 + 3x - \frac{2}{15} \\\\x - x - 3x = -\frac{2}{3} + \frac{2}{5} -\frac{2}{15}+2\\\\-3x = -\frac{2}{3}+\frac{2}{5}-\frac{2}{15}+2 \\\\-3x = \frac{(-2*5)+(3*2)}{3*5} -\frac{2}{15}+2 \\\\-3x = \frac{-10+6}{15} - \frac{2}{15}+2\\\\-3x = -\frac{4}{15} -\frac{2}{15} +2\\\\-3x = -\frac{6}{15} +2\\\\-3x = \frac{-6+30}{15}\\\\-3x = \frac{24}{15}\\\\x = \frac{\frac{24}{15}}{-3}\\\\x = -\frac{24}{45}$

Rpta ⇒ x = -24/45
