Math Problem Statement

For each system of equations, determine the true statement about its solution set.

Solution

To determine the correct statements about the systems of equations, let's analyze both sets:


First System

y=6x3andy=3(2x+1)y = 6x - 3 \quad \text{and} \quad y = 3(2x + 1)

  1. Simplify the second equation:
    y=3(2x+1)=6x+3y = 3(2x + 1) = 6x + 3

  2. The system becomes:
    y=6x3andy=6x+3y = 6x - 3 \quad \text{and} \quad y = 6x + 3

Here, the slopes (6x6x) are the same, but the yy-intercepts are different (3-3 and +3+3). Therefore, these two lines are parallel and never intersect.

Conclusion: This system has zero solutions.
Correct Statement:

"Zero Solutions: yy is equal to two different expressions."


Second System

y=2x+1andy=6x+3y = 2x + 1 \quad \text{and} \quad y = 6x + 3

  1. Compare the equations:
    y=2x+1andy=6x+3y = 2x + 1 \quad \text{and} \quad y = 6x + 3

  2. The slopes are different (22 and 66), so the lines intersect at exactly one point.

Conclusion: This system has one solution.
Correct Statement:

"One Solution: 2x+1=6x+32x + 1 = 6x + 3 has one solution."


Final Answers

  1. First System: Zero Solutions: yy is equal to two different expressions.
  2. Second System: One Solution: 2x+1=6x+32x + 1 = 6x + 3 has one solution.

Let me know if you'd like step-by-step solving for intersection points or further explanations.
