 There are 3 steps needed  to take to solve any linear equation not to stress
 
    First Step : Simplify both sides:
 
      3 ( 1.5 P + 9)- 18 = 9 ( 0.3 P + 2)
 
       4.5 P + 27-18 = 2.7 P + 18      / Here distributive law is used to simplify both sides
 
 
        2n d Step :
        
       Move variable terms to one side and constants to other.
 
         4.5 P - 2.7 P = 36 -27
         1.8 P = 9
  3rd step:
            P = 9/1.8 = 5    /  always you should end up with mx = n , X = n/m , in this case is 9/1.8
 
 
 These 3 steps always work.
 
3(1.5p+9)-18=9(0.3p+2)
 
The first step is to multiply out everything
 
3(1.5p+9)-18=9(0.3p+2)
 
(3)(1.5p) + (3)(9) - 18 = (9)(0.3p) + (9)(2)
 
4.5p + 27 - 18 = 2.7p + 18 
 
4.5p + 9 = 2.7p + 18  
 
Now combine like terms:
 
4.5p - 2.7p = 18 - 9   (Subtract 2.7p and 9 from both sides)
 
1.8p = 9                   (4.5p - 2.7p = 1.8p)
 
Can you solve for p from here?
