Linear Equations
A set of linear equations having a regula solution set is called system of coincidents linear equations.Find values of three unknowns, given three linear equations in the three unknown variables. Linear equation in three unknowns x, y, z is report of parity of form ax + by + cz + d = 0 where a, b, c, d are real numbers with a ≠ 0, b ≠ 0 and c ≠ 0.
Solve two equations in x, y
* Two equations are given.
* Removing y variable.This can also help us on system of linear equation
* Substitute value of x in any one of two equations
* Solve them in the usual way.
* Thus the values of x and y are obtained.
