3 + |1+p| = 12

 

subtract 3 from both sides

 

l 1 + p l  = 9

 

We really have these two equations......

 

1 + p   = 9                    and          1 + p  = -9

 

subtract 1 from both sides

 

p  = 8                  and                  p   = -10

 

And those are the two solutions

 

 

cool cool cool
