How to Find Linear Equations in Two Variables?
A linear equation of the form Ax + By = C. Here, x and y are variables, and A, B, and C are constants.
To solve the variables of the given equations, let's see an example to understand briefly.
Solve 2x + y = 7 and x + y = 5
2x + y = 7 ------> (1)
x + y = 5 -------> (2)
From (2), x = 5 - y ------> (3)
Substitute (3) in (1),
2(5 - y) + y = 7
10 - 2y + y = 7
10 - y = 7
y = 3 ------> (4)
Substitute (4) in (2),
x + 3 = 5
x = 2
Therefore, x = 2, y = 3
Similarly, you can try the calculator to solve the linear equation in two variables for:
- 7x + 8y = 17 and x - 16y = 4
- 11x - 17y = -18 and 12x - 15y = 8
