A system of linear equations consists of two or more linear equations in two or more variables such that all equations in the system are considered simultaneously. To find the single, unique solution of a system
x = 2 ---> (4) Substitute (4) in (2), 4x - y = 7 4(2) - y = 7 8 - y = 7 y = 1 Therefore, x = 2, y = 1 Similarly, you can try the linear equations in two variables calculator to solve the linear equation in two variables for: 7x +...
