Dau coronita!


Răspuns :

(2x-5)/3 = (2-4x)/2   /x6 
2(2x-5) = 3(2-4x)
4x - 10 = 6 - 12x 
4x + 12x = 6 + 10 
16x = 16 
x = 1
[tex] \it 2x -\dfrac{5}{3} = 2 - \dfrac{4x}{2}[/tex]



[tex]\it 2x -\dfrac{5}{3} = 2 - \dfrac{4x}{2} \Leftrightarrow 2x -\dfrac{5}{3} = 2 - 2x\Leftrightarrow 2x+2x = 2+\dfrac{5}{3} \Leftrightarrow \\\;\\ \\\;\\ \Leftrightarrow 4x = \dfrac{11}{3} \Leftrightarrow x = \dfrac{11}{12}[/tex]
