cramer rule
Using cramer's method solve the system of linear equations
x + y + z = 1
ax + by + cz = 1
a^2x + b^2y + c^2z = 1
where a,b,c are distinct real numbers

Hi,

Well first off do you know what Cramer's method, or Cramer's Rule is? The setup is half the battle. Can you do any part of the problem yourself? Once I know where you are on this I can decide where to start helping.

cramer's rule is

$
x=\frac{|A_x|}{|A|} y=\frac{|A_y|}{A} z=\frac{|A_z|}{|A|}
