If x = 1- 4t and y = 2t - 2, then for what value of t does x = y?  Answers:  A) 5 / 2  B) 1 / 2  C) 2 / 3  D) 2 / 5  E) 0

Rationale: we are given x = 1 – 4 t and y = 2 t – 2 , and we need to determine the value for t when x = y . we should notice that both x and y are already in terms of t . thus , we can substitute 1 – 4 t for x and 2 t – 2 for y in the equation x = y . this gives us : 1 – 4 t = 2 t – 2 3 = 6 t 1 / 2 = t the answer is b .
Answer: B
