Răspuns:
a) [tex] \frac{x}{4} = \frac{2}{3} = > x = \frac{4 \times 2}{3} = \frac{8}{3} [/tex]
b) [tex] \frac{y + 1}{ 3} = \frac{4}{12} = > y + 1 = \frac{3 \times 4}{12} = > y = 0[/tex]
Explicație pas cu pas:
a) [tex] \frac{ \frac{8}{3} }{4} = \frac{2}{3} < = > \frac{2}{3} = \frac{2}{3} [/tex]
b) [tex] \frac{0 + 1}{ 3} = \frac{4}{12} < = > \frac{1}{3} = \frac{1}{3} [/tex]
