# The equation x = 7, in two variables, can be written as

A. 1. x + 1. y = 7

B. 1. x + 0. y = 7

C. 0. x + 1. y = 7

D. 0. x + 0. y = 7

Answer :

A. Simplifying the equation we get x + y = 7

B. Simplifying the equation we get x + 0y = 7 which is equal to x = 7

C. Simplifying the equation we get y = 7

D. simplifying the equation we get 0x + 0y = 7 which is not possible.

Hence B is the correct answer.
