Simultaneous Equations

Mathematics · Algebra · conceptual

Understand that two linear equations can be solved simultaneously by finding the point where their graphs intersect, and interpret this graphically and algebraically as the pair of values satisfying both equations

Sign in to track this

What mastery looks like

  • Explain that the intersection of two lines represents values satisfying both equations
  • Find the approximate solution to a pair of simultaneous equations by reading a graph
  • Verify a proposed solution by substituting into both equations

Check your understanding

Can Simultaneous Equations explain that solving two equations simultaneously means finding the one pair of values that satisfies both at once — and show what that looks like on a graph?
