x +1/12=2/3 atunci x=


Răspuns :

x + 1 / 12 = 2 / 3
aducem la acelasi numitor care este 12
12x + 1 = 8
12 x = 8 - 1
12 x = 9
x = 9 / 12
[tex]x + \frac{1}{12} = \frac{2}{3} \\ \\ x = \frac{2}{3} - \frac{1}{12} \\ \\ x = \frac{16}{24} - \frac{2}{24} \\ \\ x = \frac{14}{24} [/tex]

[tex]x = \frac{7}{12} [/tex]
