Question

Rezolvați ecuația: x+5/3-x+15/6=1/3-x+3/4,x e R​

Answer 1

Răspuns:

x+5/3-x+15/6=1/3-x+3/4,x e R​

2(x+5)/3- (x+15)/6= 1/3- (x+3)/4

(2x+10)/6- (x+15)/6= 4/12- 3(x+3)/12

(2x+10-x-15)/6= (4-3x-9)/12

(x-5)/6= (-3x-5)/12

12(x-5)= 6(-3x-5)

12x-60= - 18x-30

12x+18x= - 30+60

30x= 30

x= 30/30

x= 1
