Question

Identify a linear equation in two variables among the following:

  1. 33z + 5 = z
  2. 33(x + y) = 0
  3. 33x + 5x= 0
  4. 33y + 5 = 0

hintHint:

A n space e q u a t i o n space i s space s a i d space t o space b e space l i n e a r space e q u a t i o n space i n space t w o space v a r i a b l e s space i f space i t space i s space w r i t t e n space i n space t h e space f o r m space o f space a x space plus space b y space plus space c equals 0 comma
