if x = 1 - 5 t and y = 2 t - 1 , then for what value of t does x = y ?
"we are given x = 1 – 5 t and y = 2 t – 1 , 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 – 5 t for x and 2 t – 1 for y in the equation x = y . this gives us : 1 – 5 t = 2 t – 1 2 = 7 t 2 / 7 = t the answer is d ."
