1/3+3/4×(x+2/3=13/12
1/2 – 3/5x2 + 6/45=3/10
-3/5 x2=3/10-1/2-6/45
-3/5 x2= (27-45-12)/90
-3/5 x2= -30/90
-3/5x2= -1/3
3/5x2= 1/3
X2= (1/3) / (3/5)
X2= 5/9
raiz de x2 = raiz de 5/3

1/3+3/4x+1/2= 13/12
3/4x=13/12-1/2-1/3
3/4x=(13-6-4)/12
3/4x = (13-10)/12
3/4x= 3/12
3/4x=1/4
x=(1/4)/(3/4)
x=4/12
x= 1/3
