Question

Doar punctul a va rog! Rpd

Answer 1

(x-1) / (2/2 +1/2) = (7/3-3/3) / (6/2-3/2)

(x-1) / 3/2 = 4/3 / 3/2

x-1 = 4/3

x= 4/3 +1

x= 4/3 +3/3

x=7/3

Answer 2

$\it \dfrac{x-1}{1+\dfrac{1}{2}}=\dfrac{\dfrac{7}{3}-1}{3-\dfrac{3}{2}} \Rightarrow \dfrac{x-1}{\dfrac{3}{2}}=\dfrac{\dfrac{7}{3}-1}{\dfrac{3}{2}} \Rightarrow x-1=\dfrac{7}{3}-1 \Rightarrow x=\dfrac{7}{3}$
