[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]
