Question

Determinati numarul natural x care verifica egalitatile                                                                             [(x+360:4)x5+700]:600=2  va rog daca ma puteti ajuta

Answer 1

[(x+90)x5+700]=1200
(x+90)x5+700=1200
(x+90)x5=500
x+90=100
x=100-90
x=10

Answer 2

[(x+360:4)x5+700]:600=2    
(x+90)x5+700=600x2    
(x+90)x5+700=1200     
(x+90)x5=1200-700      
(x+90)x5=500      
(x+90)=500:5      
(x+90)=100     
x+90=100     
x=100-90    
x=10
