Chapter 3- Simultaneous equations

Solving simultaneous equations by Elimination method

 Solving Simultaneous linear equations by substitution method 

Solving one linear one quadratic equation simultaneously

Example

Given the simultaneous equations

                  2x + y = 1

                   x^2 - 4ky + 5k = 0

where k is the non zero constant

(a) Show that 

                  x^2 + 8kx + k = 0

Given that x^2 + 8kx +k =0 has equal roots

(b) Find the value of k

(c) For this value of k, find the solution of the simultaneous equations.
