Answer:

[tex]p=-8[/tex]

Step-by-step explanation:

[tex]7(p + 3) + 9 = 5(p - 2) - 3p\\[/tex]

1. distribute

[tex]7p +21 +9 = 5p -10 - 3p\\[/tex]

2. collect like terms

[tex]21+9+10 = 5p - 3p - 7p[/tex]

3. solve

[tex]40 = -5p\\-8 = p[/tex]

Answer:

p = -8

Step-by-step explanation:

step 1

((7•(p+3))+9)-(5•(p-2)-3p)  = 0

step 2

(7 • (p + 3) +  9) -  (2p - 10)  = 0

step 3

 5p + 40  =   5 • (p + 8)

step 4

5 • (p + 8)  = 0

 5   =  0  (This equation has no solution)

step 5

 p+8 = 0

p = -8 (This is the answer)
