1/2× x+ 1/4= 1/3
1/2×x=1/3-1/4
1/2×x=4×1-3×1 tot asta supra/12
1/2×x=4-3 totul supra /12
1/2×x=1/12
x=1/12 :1/2
x=1/12× 2/1
x=1×1 totul supra /6×1
x=1/6


verificare

1/2×1/6+1/4=
=1×1 totul supra/2×6 + 1/4=
=1/12+1/4=
=1+3×1 totul supra/12=
=1+3 totul supra/12=
=4/12 (simplificat cu 4)=
=1/3 (adevarat )
