Question: Solve the equation. -6p - 21 = 3p - 12

---------------------------------

Pre-requisite Knowledge

• When in an equation, a number with a +ve sign goes to the other side of the equal symbol, the number becomes -ve.

• EG: 12 + x = 1 when shifting happens, it results to x = 1 - 12

• When in an equation, a number with a -ve sign goes to the other side of the equal symbol, the number becomes +ve.

• EG: -12 + x = 1 when shifting happens, it results to x = 1 + 12

---------------------------------

Answer

-6p - 21 = 3p - 12

-6p- 3p = - 12 + 21  

      -9p =  9

         p = 9/-9
