This is about simultaneous equations.
<u><em>p = s has been proved below. </em></u>
p + q = 25 - - - (eq 1)
r + s = 25 - - - (eq 2)
q = r - - - (eq 3)
- Let's put r for q in eq 1 to get;
p + r = 25 - - -(eq 4)
- Let's subtract eq 2 from eq 4;
(p + r) - (r + s) = 25 - 25
p + r - r - s = 0
p - s = 0
p = s
