[tex]20p + -5p - -17 = -13[/tex] 

[tex]20p + -5p - -17 = -13:p[/tex]  [tex]|Solve \ for \ p|[/tex] 

[tex]20p-5p+17=-13[/tex] 

[tex] 15p+17=-13 [/tex] 

[tex] 15p=-13-17 [/tex]  [tex]|Subtract \ 17 \ from \ both \ sides|[/tex] 

[tex] 15p=-30 [/tex] 

[tex] 15p/15=-30/15 [/tex]  [tex]|Divide \ both \ sides \ by \ 15|[/tex] 

[tex] p=-2 [/tex]
