# Cramer's Rule Exercises

### Example 1

Solve for *x* and *y* using Cramer's Rule:

2*x* – 2*y* = 5

-*x* – 3*y* = 0

### Example 2

Solve for *x* and *y* using Cramer's Rule:

3*x* + *y* = 9

5*x* – 2*y* = 3

### Example 3

3. Solve for *x* and *y* using Cramer's Rule:

4*x* + *y* = -2

-2*x* – (-5*y*) = -3
