I appreciate your help
- 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
0.2x + 0.4y = 1.7 and 8.3x - 6.3y = -4.3
x/3 - y/5 = 4 and 3x/4 + 2y/3 = 6
4x = 8 and 5y = 15
4x = 8
5y = 15
4x/4 = 8/4
x = 2
5y = 15
5y/5 = 15/5
