Question

Which of the following is not a linear equation?
a.) x+y+1=0
b.) xy-3=x
c.) 3(x-1) = 2(x+2)
d.) 4x-1=2x
Screenshot given for reference or help.

Answer 1

Answer:

x+y+1=0 is not a linear pair

Answer 2

(d) 3 (x - 1) = 2 (x + 2)

3x - 3 = 2x + 4

3x - 2x = 4 + 3

x = 7

This cannot be termed as equation, because it depicts the value of the variable x.
