Solve for p. 20p + -5p – -17 = -13
STatiana [176]
20p + -5p - -17 = -13 

20p + -5p - -17 = -13:p  |Solve \  for \ p| 

20p-5p+17=-13 

&#10;15p+17=-13&#10; &#10; 

&#10;15p=-13-17&#10; &#10;  |Subtract \ 17 \ from \ both \ sides| 

&#10;15p=-30&#10; &#10; 

&#10;15p/15=-30/15&#10; &#10;  |Divide  \ both \ sides \ by \ 15| 

&#10;p=-2&#10; &#10;
