Answer:
The given equation is
y =
x
→ 
reciprocating both sides, we get
→
............(1)
→ Here x and y are Directly proportional to each other.
which means ,
→ x = k y , where k is constant of proportionality.
Or ,
= k ............................(2)
Equating (1) and (2),
k =
4x + 2y = 14
8x + y = 10
7 - 2x = 10 - 8x
7 + 6x = 10
6x = 3
x = 1/2
y = 6

In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 32, which is the number 9.
