Question

For the systems of linear equations in questions 1-3
- Determine how many solutions exist
- Use either elimination or substitution to find the solutions (if any)
- Graph the two lines, labeling the x-intercepts, y-intercepts, and points of intersection

1. 4x = 8 and 5y = 15

2. 0.2x + 0.4y = 1.7 and 8.3x - 6.3y = -4.3

3. x/3 - y/5 = 4 and 3x/4 + 2y/3 = 6
