The solution of a linear equation in two variables is a pair of values (x, y), one for ‘x’ and the other for ‘y’, which makes the two sides of the equation equal. Eg: If 2x + y = 4, then (0,4) is one of its solutions as it satisfies the equation. A linear equation in two variables has infinitely many solutions.
22 sty 2024 · Two linear equations in the same two variables are called a pair of linear equations in two variables. The most general form of a pair of linear equations is: a 1 x + b 1 y + c 1 = 0; a 2 x + b 2 y + c 2 = 0. where a 1, a 2, b 1, b 2, c 1 and c 2 are real numbers, such that a 12 + b 12 ≠ 0, a 22 + b 22 ≠ 0.

Introduction: Pair of Linear Equations in two Variables. Answer. • Linear equation in two variables: An equation in the form of ax + by + c = 0 where x and y are variables and a, b, c are real numbers (a≠0, b≠0) is called linear equation in two variable. Example: (i) 3x + 4y + 4 = 0. (ii) 2/3 x + y = 0.
Linear Equation. A linear equation in two variables is defined as an equation with the form $ {\text {ax}} + {\text {by}} + {\text {c}} = 0$, where $ {\text {a}}, {\text {b}}$ and $ {\text {c}}$ are real numbers and both a and $ {\text {b}}$ are nonzero.
