-0.75 + -2 = 0.25p 
 -0.75 + -2 = -2.75 -2.75 = 0.25p 
 Solving -2.75 = 0.25p 
 Solving for variable 'p'. 
 Move all terms containing p to the left, all other terms to the right. Add '-0.25p' to each side of the equation.
 -2.75 + -0.25p = 0.25p + -0.25p 
 0.25p + -0.25p = 0.00 
-2.75 + -0.25p = 0.00 Add '2.75' to each side of the equation. 
-2.75 + 2.75 + -0.25p = 0.00 + 2.75
 Combine like terms: -2.75 + 2.75 = 0.00 
0.00 + -0.25p = 0.00 + 2.75 -0.25p = 0.00 + 2.75
 Combine like terms: 0.00 + 2.75 = 2.75 
-0.25p = 2.75
 Divide each side by '-0.25'. p = -11 
 p = -11
