Question

Решите плиз 3,2y - 2,7y = 0,6
3,7z - z = 0,54
зарание спасибо"

Answer 1

$3.2y-2.7y=0.6\ 0.5y=0.6\ x=1.2\ \ 3.7z-z=0.54\ 2.7z=0.54\ z=0.2$

Answer 2

3,2y - 2,7y = 0,6
(3,2 - 2,7)*y = 0.6
y = 0.6 / (3.2 - 2.7) = 0.6 / 0.5 = 6 / 5 = 1.2

3.7z - z = 0,54
(3.7 - 1)*z = 0.54
z = 0.54 / (3.7 - 1) = 0.54 / 2.7 = 54 / 270 = 2/10 = 0.2
