Bună !!
•Rezolvarea:
**mai jos↓
[tex]a) \: \frac{2}{x} = \frac{3}{9} \\ 3x = 9 \times 2 \\ 3x = 18 \\ x = 18 \div 3 \\ x = 6[/tex]
[tex]b) \: \frac{x + 1}{6} = \frac{10}{4} \\ 10 \times 6 = (x + 1) \times 4 \\ 60 = 4x + 4 \\ 4x = 60 - 4 \\ 4x = 56 \\ x = 56 \div 4 \\ x = 14[/tex]
Succes !!:)

Răspuns: a) x = 6 b) x = 14
a) 2/x = 3/9
2 • 9 = x • 3
18 = x • 3
x • 3 = 18
x = 18 ÷ 3
x = 6
b) x+1/6 = 10/4
( x + 1 ) • 4 = 6 • 10
( x + 1 ) • 4 = 60
4x + 4 = 60
4x = 60 - 4
4x = 56
x = 56 ÷ 4
x = 14
Succes! :D
