Which of the following are Pair of Linear Equation in two variables? Options: A . &nbsp 2 x + y = 2 ; 3 x − z = 2 B . &nbsp 12 x + 4 y + 3 = 0 ; 4 x + 4 y + 4 = 0 C . &nbsp x + 2 = 0 ; a + 2 b = 0 D . &nbsp x + y − 3 = 0 ; 4 a + 2 b + 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.
