Question

[ 495-(x:3)]*5=975 va rog mult ca nu pot repede dau coroana si 29 de puncte

Answer 1

(495- $\frac{x}{3}$ )  * 5= 975  (inmultim paranteza cu 5)

2475- $\frac{5x}{3}$ = 975 ( inmultim tot calculul cu 3 ca sa scapam de fractie):

7475-5x=2925
7475-2925=5x
4550=5x
x= 4550:5
x= 910

Answer 2

[495-(x:3)]×5=975
[495-(x:3)]=975:5
[495-(x:3)]=195
495-195=x:3
300=x:3
X=300×3
X=900
