  • 1. 3.2 Solve Linear Systems Algebraically
    The Substitution Method
  • 2. Substitution
    To replace one thing with another of equal value.
  • 3. Substitution
    To replace one thing with another of equal value.
  • 4. Solve a Linear System Using Substitution
    Identify a term
    with a coefficient
    of 1 or -1
  • 5. Solve a Linear System Using Substitution
    Solve that equation
    for that variable
    Substitute this
    expression in the
    OTHER equation
    Solve
  • 6. Solve a Linear System Using Substitution
    Substitute this
    value in the
    altered equation
    Simplify
  • 7. Solve a Linear System Using Substitution
    (-30, 11)
    Write the solution
    as an ordered
    pair
  • 8. Example 2
    (4, 4)
  • 9. Example 3

    Means the
    solution
    does not
    exist
    Nonsense!
  • 10. Example 3
    y=1/2x- 7/2
    Means there
    are infinitely
    many
    solutions
    True, but not helpful.
