  8. Elimination Method Given the Equations

  9. Elimination Method Given the Equations

  10. Elimination Method Given the Equations

  11. Linear equations The intersection of two lines is one and only one point, unless the lines are parallel or the same line.

  12. What is the Solution(s) if the lines are Parallel lines not meet, so no solution The Same line or lines that are onto, meet at all points on the lines, Infinitely many solutions.
