linear equations with two variables

Let us learn about linear equations with two variables
-->x = 1, y = 1 is a solution of 2x + 3y = 5 2(1) + 3(1) = 5
x = -2, y = 3 is also a solution of 2x + 3y = 5
2(-2) + 3(3) = 5
-4 + 9 = 5
You can find many more solutions for 2x + 3y = 5
A system of linear equations is 2 or more linear equations that are being solved concurrently.
A linear equation in 2 variables is of the form
ax + by = c,
Where a ≠ 0, b ≠ 0

Linear equations in 2 Variables Example

2x + 3y = 5,
x - 2y = 6,
-6x + y =8
A pair of values of y & x that satisfy a given linear equation in 2 variables is said to be its solution.
