Question

Cele încercuite va rog dau coronița am pus-o de 3-4 ori urgent!!

Answer 1

4. $x = \frac{3}{7} \times y$
$\frac{y}{2 } = x + 2$
$y = 2 \times x + 4$
$y = \frac{6}{7} \times y + 2$
7y = 6y + 14
y=14
x= 14/2 -2= 5
5. 7 primul borcan
5 al 2-lea
6. x+x+1=42
2x+1=42
2x = 41
x= 41/2 = 20.5
x+1 = 21.5
