DISCUSS: A Family of Equations The equation 3x + k – 5 = kr – k + 1 is really a family of equations, because for each value of k, we get a different equation with the unknown x. The letter k is called a parameter for this family. What value should we pick for k to make the given value of x a solution of the resulting equation? (a) x = 0 (b) x = 1 (c) x= 2
