  3. Steps for Substitution: 1. Find your SUB (do you know what y is?  x is?) 2. SUB into other equation (now you should have all y's or all x's) 3. Solve the equation  (Distribute, Combine Like Terms, +or -, Mult or Divide) 4. Now that you know the value of one variable, plug it back in to find the other one.
