12 – 8 - 3 = 1


               3 + 1 -3 = 1

               LHS = RHS

               3. If we multiply the same number to both the sides.


               We can multiply the same number on both the sides of a balanced equation; the
               equation will remain the same.


               12 – 8 = 4

               If we multiply 3 to both the sides,


               LHS= 12-8= 4x3=12

               RHS= 4x3=12

               So


               LHS = RHS

               4. If we divide the same number from both sides.


               We can divide the same number from both the sides of a balanced equation; the
               equation will remain the same.


               12 – 8 = 3 + 1

               If we divide both the sides by 2,

               LHS= (12 – 8) ÷ 2 = 4 ÷ 2 = 2


               RHS=(3 + 1) ÷ 2 = 4 ÷ 2 = 2

               So


               LHS = RHS
