Question

2,5+1 SUPRA4 X=5 REZOLVATI Q

Answer 1

2,5 + $\frac{1}{4} x = 5$ 

transformam 2,5 in fractie = $\frac{25}{10}$

$\frac{25}{10} + \frac{x}{4} = 5$  aducem la numitor comun 20

$\frac{50}{20} + \frac{5x}{20} = \frac{100}{20}$  scapam de numitor

50 + 5x = 100
 
5x = 100 -50

5x = 50

x= 50: 5

x= 10
