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?
