Va rod frumos exercitiul 2. Repede ajutati-ma!

Answer 1

a)$\frac{x - 1}{1 + \frac{1}{2} } = \frac{ \frac{7}{3} - 1 }{3 - \frac{3}{2 } }$
$\frac{x - 1}{ \frac{3}{2} } = \frac{ \frac{4}{3} }{ \frac{3}{2} }$
$x - 1 = \frac{4}{3}$
$x = \frac{4}{3} + 1$
$x = \frac{7}{3}$

b)$\frac{2x + 1}{4x + 3} = \frac{1}{3}$
$3(2x + 1) = 1(4x + 3)$
$6x + 3 = 4x +3$
$2x =0$
$x = 0$
