Question

Rezolva ecuatiile: x intregi si 1/2+ x intregi si 1/3= 10 intregi si 5/6. Vaa rog !!! E urgeeeeeeent!!! Dau coroana

Answer 1

x intregi si 1/2=x+1/2=(2x+1)/2
x intregi si 1/3=x+1/3=(3x+1)/3
10 intregi si 5/6=10+5/6=65/6
(2x+1)/2+(3x+1)/3=65/6
Inmultim ecuatia cu 6 ca sa scapam de numitor si obtinem:
3(2x+1)+2(3x+1)=65
6x+3+6x+2=65
12x+5=65
12x=60
x=5
