Question

Calcula :$\frac{3x-1}{5} +\frac{x+2}{10} =\frac{x}{3}$

Answer 1

Respuesta:

$\frac{3x - 1}{5} + \frac{x + 2}{10} = \frac{x}{3} \\ 30( \frac{3x - 1}{5} + \frac{x + 2}{10} ) = 30 \times \frac{x}{3} \\ 6(3x - 1) + 3(x + 2) = 10x \\ 18x - 6 + 3x + 6 = 10x \\ 21x = 10x \\ 21x - 10x = 0 \\ 11x = 0 \\ x = 0$
