Solution for p-(s-t)=p equation:


Simplifying
p + -1(s + -1t) = p
p + (s * -1 + -1t * -1) = p
p + (-1s + 1t) = p

Add '-1p' to each side of the equation.
p + -1s + -1p + 1t = p + -1p

Reorder the terms:
p + -1p + -1s + 1t = p + -1p

Combine like terms: p + -1p = 0
0 + -1s + 1t = p + -1p
-1s + 1t = p + -1p

Combine like terms: p + -1p = 0
-1s + 1t = 0

Solving
-1s + 1t = 0

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-1t' to each side of the equation.
-1s + 1t + -1t = 0 + -1t

Combine like terms: 1t + -1t = 0
-1s + 0 = 0 + -1t
-1s = 0 + -1t
Remove the zero:
-1s = -1t

Divide each side by '-1'.
s = t

Simplifying
s = t
