Solving Systems of Equations Algebraically

  • You can solve a system of equations by substitution or by elimination.

  • Sometimes each equation must be multiplied before elimination can be used.

  • If you obtain an equation that is always true, the system has an infinite number of solutions.

  • If you obtain an equation that is never true, the system has no solution.
