Question

rezolva ecuatia 37 pe 12 -x =21 pe 6

Answer 1

$\frac{ 37}{12} - x = \frac{21}{6} \\ \frac{37}{12} - x = \frac{7}{2} \\ \frac{37}{12} - \frac{7}{2} = x \\ \frac{37}{12} - \frac{42}{12} = x \\ - \frac{5}{12} = x \\ = > x = - \frac{5}{12}$

Answer 2

37 / 12 -x =21 / 6  → i - a aduc la acelas numitor comun(12)
37 - 12 x = 42
12 x = 37 - 42
x = - 5/12
