[tex] \frac{3x + 2}{2x - 4} = \frac{5}{6} [/tex]


Răspuns :

[tex] \frac{3x + 2}{2x - 4} = \frac{5}{6} \\ 6(3x + 2) = 5(2x - 4) \\ 18x + 12 = 10x - 20 \\ 18x - 10x = - 20 - 12 \\ 8x = - 32 \\ x = - \frac{32}{8} \\ x = - 4[/tex]

5•(2x-4) = 6•(3x+2)
10x-20 = 18x+12
10x-18x = 20+12
-8x = 32
x = (-4)
