x + y = 0.25                Subtract y from both sides.

x = 0.25 - y

 

x/y = 0.25                   Substitute (0.25 - y) in for x.

(0.25 - y)/y = 0.25       Distribute 1/y.

0.25/y - y/y = 0.25

0.25/y - 1 = 0.25         Add 1 to both sides.

0.25/y = 1.25              Multiply both sides by y.

0.25 = 1.25y               Divide both sides by 1.25.

0.2 = y

 

x = 0.25 - y                Substitute 0.2 in for y.

x = 0.25 - 0.2

x = 0.05

 

Just like Guest found. This is just an explanation.
