Question

Va rog repede 2 si 3

Answer 1

Ex 2.
[tex] \frac{3)2x-1}{2}- \frac{2)x}{3} = \frac{x+3}{6} \\ \frac{6x-3-2x}{6} = \frac{x+3}{6} |*6 \\ 4x-3=x+3\\ 3x=6\\x=2[/tex]

Ex 3.
x=lungimea drumului
[tex] \frac{1}{3} x+2= \frac{1}{2} x \\ \frac{2)1}{3} x- \frac{3)1}{2} x+2=0\\ \frac{2x-3x}{6} +6)2=0\\ \frac{-x+12}{6}=0\\-x+12=0\\-x=-12\\x=12 [/tex]
