4.2x - 1.4y = 2.1 |multiply both sides by 10
42x - 14y = 21 |subtract 42x from both sides
-14y = 21 - 42x |change signs
14y = 42x - 21 |divide both sides by 14
y = 3x - 1.5

Equating "equal" as symmetrical:
Two windows of the same size and placed in the same position is considered symmetrical. In an example where one window is placed at a certain distance from a wall and a certain distance from the floor, another window of the same size is also placed in the opposite side of the first window (based on a constant center) with the same distance from the floor and wall. The two windows can be considered equal.
