Question

Afla numerele necunoscute: a) 3*x=2*6 ;36:x=2*3 x:6=80:8;b)x*2=3*6;

Answer 1

3*x=2*6
3*x=12
x=12:3
x=4

36:x=2*3
36:x=6
x=36:6
x=6


x:6=80
x=80*6
x=480

x*2=3*6
x*2=18
x=18:2
x=9

Answer 2

3 × x = 2 × 6 
x = 12 : 3 
x = 4 

36 : x = 2 × 3
36 : x = 6 
x = 36 : 6 
x = 6 → deimpartitul 

 x : 6 = 80 : 8
x : 6 = 10 
x = 10 × 6 
x = 60 → deimpartitul 

b) x × 2 = 3 × 6
x × 2 = 18 
x = 18 : 2 
x = 9 → primul factor
