# solving system of linear equations

i) Solve he following equation by the quadratic formula :

3X^2 + 4X -23 = 0

ii) Find the values of x and y that satisfy the equations here given

( use the simultaneous equation method ) :

3x + 2y = 22

2x + 3y = 23

iii) Solve graphically the following equations: show the graph as a part of the solution.

x+y=5

x-y=1

iv) Using determinants solve the following equations :

a) 2x+y = 3

x+y = -2

b) 4x + 2y -z = 9

2x + y = 4

x + 2y - 2z = 2
