1. x = 4       2. x = 8     3. p = 30

Step-by-step explanation:

1.    x + 7 = 11          check:      (4) + 7 = 11

         - 7   - 7                                  11 = 11

        x  =  4

2.   x - 12 = -4         check:       (8) - 12 = -4

        + 12   + 12                                -4 = -4

      x = 8

3.  multiply p/5 by 5 it cancels each other out and then you do the same thing to the other side. multiply 6 by 5 and you get 30  

check:    (30)/5 = 6

                      6 = 6

             30 divided by 5 equals 6  

x equals 1

f(4)=f(×)

x=1
