Consider the system of linear equations
X + ay = 1
2x + 8y = b
Where a and b are real numbers.
(a) Write out the augmented matrix for this system of linear equations.
(b) Use elementary row operations to reduce the augmented matrix to row-echelon form.
(c) Determine for what values of a and b does the system have infinitely many solutions.
(d) Determine for what values of a and b does the system have no solution.
(e) Determine for what values of a and b does the system have an unique solution.
Example of Subtraction of Fractions: 1/3 + 1/6 + 1/8 = ____ Using trial & error we could search that 24 is the LCD or smallest number in which 3, 6, and 8 will all divide w
sin10+sin20+sin30+....+sin360=0 sin10+sin20+sin30+sin40+...sin180+sin(360-170)+......+sin(360-40)+sin(360-30)+sin(360-20)+sin360-10)+sin360 sin360-x=-sinx hence all terms cancel
