Sagot :

Answer:

[tex]\boxed{\sf p=-5}[/tex]

Step-by-step explanation:

[tex]\sf 3p - 8 = -23[/tex]

First, rearrange unknown terms to the left side of the equation:

[tex]\sf 3p=-23+8[/tex]

Add -23 + 8 = -15

[tex]\sf 3p=-15[/tex]

Divide both sides of the equation by the coefficient of variable "3" :

[tex]\sf \cfrac{3p}{3} =\cfrac{-15}{3}[/tex]

Cross out common factor:

[tex]\sf p=-5[/tex]
