Question

3 ways answer equal 4a-12

Answer 1

Answer:

1. You could equal the equation to 0 and solve
2. insert values for a until you get 0
3. equal it to zero then subtract by 4a to put it on the other side and solve.

Step-by-step explanation:

1. 4a - 12 = 0

             +12   +12

        4a = 12

        /4      /4

        a = 3

     2. 4a-12 (just insert values until you get 0) (1,2,3,4,...)

     3. 4a - 12 = 0

         -4a         -4a

         -12 = -4a

          /-4     /-4

         a = 3
