  • Simultaneous equations are sets of equations that share a solution
  • Equations are only true when the variables have specific values
  • Sets of equations involving the same variables can be solved simultaneously
  • Solving simultaneous equations involves finding values for the variables that satisfy both equations
  • The solution to a pair of simultaneous equations includes both variables
  • A single equation with two variables can have infinitely many solutions
  • A second equation is needed to find a unique solution for both equations
  • Simultaneous equations can have multiple solutions, including up to two solutions for a linear equation and a quadratic equation.
