Question

Which of the following are Pair of Linear Equation in two variables?

Options:

A . 2x+y=2;3x−z=2

B . 12x+4y+3=0;4x+4y+4=0

C . x+2=0;a+2b=0

D . x+y−3=0;4a+2b+c=24

Answer: Option B
:
B
Two linear equations in same two variables are called pair of linear equation in two variables.

12 x + 4 y + 3 = 0 a n d 4 x + 4 y + 4 = 0

are linear equations in same two variables.
