Ma ajutati va rog la acest exercitiu :
0.5x-1=cu 6 supra 24


Răspuns :

[tex] \frac{5x}{10} -1= \frac{6}{24} \\ \\ \frac{x}{2} -1= \frac{1}{4} \\ \\ \frac{2x}{4} - \frac{4}{4} = \frac{1}{4} \\ \\ 2x-4=1 \\ 2x=5  \\ x=2,5[/tex]
0,5X - 1 = 6/24
5X/10 - 1 = 1/4
X/2 - 1 = 1/4 |×4
2X - 4 = 1
2X = 5
X = 5:2
X = 2,5
