Simultaneous equations

    Cards (2)

    • Algebraic solution:
      1. Number each solution
      2. If necessary, multiply the equations so that the coefficients of one unknown are the same
      3. Add or subtract the equation to eliminate the unknown
      4. Once one unknown is found use it to find the other
      5. Check both answers via substituting both values into the other
    • If a pair of simultaneous equations involve an x^2 or an y^2 term, you need to solve them using substitution. Remember to number the equations to keep track of your working.
