Question

aflati x,y,z daca x supra 3 = y supra 6 ,y supra 2 = z si x + 2y + z = 18 ​

Answer 1

Răspuns:

$\frac{x}{3} = \frac{y}{6} = > 6x = 3y = > 6 \times 3 = 3 \times 6 = > x = 3 \: \: y = 6.$

$\frac{y}{2} = z = > z = \frac{6}{2} = 3.$

$x + 2y + z = 18 = > 3 + 2 \times 6 + 3 = 18 = > 3 + 12 + 3 = 18 = > 18 = 18.$
