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.
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
This solution provides different methods of solving system of linear equations, such as graphing, determinant, and simultaneous equation method. The solution is detailed and well presented.
