Cramer's Rule
Cramer's Rule may be used for solving the system of equations:
ax + by = e
cx + dy = f
cx + dy = f
The solutions for x and y may be expressed as:
For the case of e = f = 0:
the trivial solution of x = y = 0 always exists.
For the case of e = f = 0:
ax + by = 0
cx + dy = 0
cx + dy = 0
the trivial solution of x = y = 0 always exists.
Example:
3x + 2y = 18
4x + 6y = 48
Using Cramer's Rule, solve the set of equations:
3x + 2y = 18
4x + 6y = 48
Solution:
