For the systems of linear equations in this question
- 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
x + y = 3 and y = x + 3
X+X+3=3
2X=0
X=0
Y=3...HENCE THERE IS ONLY ONE UNIQUE SOLUTION.

y = 2x + 3 and y = -x - 4
-X-4=2X+3
2X+X=-4-3=-7
3X=-7
X=-7/3
Y=-(-7/3)-4=7/3-4=(7-12)/3=-5/3
HENCE THERE IS ONE UNIQUE SOLUTION.
