Question

3+3*{3+3*[3+3*(3-3: y)]}=3*31
Va rog sa ma ajutati

Answer 1

3+3x{3+3x[3+3x(3-3:y)]}=3x31
3+3x{3+3x[3+3x(3-3:y)]}=93
3x{3+3x[3+3x(3-3:y)]}=93-3
3x{3+3x[3+3x(3-3:y)]}=90
{3+3x[3+3x(3-3:y)]}=90:3
3+3x[3+3x(3-3:y)]=30
3x[3+3x(3-3:y)]=30-3
3x[3+3x(3-3:y)]=27
3+3x(3-3:y)=27:3
3+3x(3-3:y)=9
3x(3-3:y)=9-3
3x(3-3:y)=6
3-3:y=6:3
3-3:y=2
3:y=3-2
3:y=1
y=1x3
y=3

Mult succes la scoală
