As stated, there is nothing to rationalise.
2 peas in a pod
2=p in a q
p = -1
p + (-2) = 1 so p - 2 = 1 Add two to both sides: p = 3
a = L x W: area equals length times the width. p = 2L + 2W: perimeter equals 2 times the length plus 2 times the width so L = (p - 2W)/2

22
p+2 = 2-3p p+3p = 2-2 4p = 0 p = 0
p = -1
PQR P=2 Q=4 R=5 2 x 4 x 5 = 40
p + (-2) = 1 so p - 2 = 1 Add two to both sides: p = 3
no it equals one :P
Solving by elimination: p = 3 and q = -2
3/p = 6 p = 3/6 = 1/2 3/q = 15 q = 3/15 = 1/5 p - q = 1/2 - 1/5 p - q = 5/10-2/10 = 3/10
