Question

Rezolvati in R ecuația: 3/5 (x/6 - 2) =x/2.
Va rog este urgent!

Answer 1

Răspuns:

x=0

Explicație pas cu pas:

$\frac{3}{5} \times \frac{x}{6 - 2} = \frac{x}{2} \\ \frac{3}{5} \times \frac{x}{4} = \frac{x}{2} \\ \frac{3x}{20} = \frac{x}{2} \\ 6x = 20x \\ 6x - 20x = 0 \\ - 14x = 0 \\ x = 0$

Answer 2

$\frac{3}{5} ( \frac{x}{6} - 2) = \frac{x}{2} \\ \frac{3x}{30} - \frac{6}{5} = \frac{x}{2} \\ \frac{3x - 36}{30} = \frac{x}{2} \\ \frac{3x - 36}{30} = \frac{15x}{30} \\ 3x - 36 = 15x \\ - 36 = 12x \\ x = - 3$
