[ WP ] You 've been trapped in Y location for Z hours , solve for X to escape the algebra zone .

Three days ago, we found the final puzzle. All the other puzzles were leading to this one. If we got it right, we could have escaped. 
 
 *If we got it right. * 
 
 I sit on the edge of the cliff, staring into the distance. Alone. The waves lap gently against the shore. Less than a mile off the coast, a small skinny island stands awkwardly in the ocean. 
 
 I scream at the ocean. “ We couldn ’ t be wrong! There ’ s no way – we scoured every nook of this wretched fucking puzzle. There was only one right answer. Only one. Only one… ” Tears well up in my eyes. I fall to the ground. Dozens of equations were etched onto the soil. We've checked the math a hundred times. 
 
 The image of Sam's smile fills my mind. *Do n't worry, Jen, * he'd say. *The two of us will be out of this place in no time. * 
 
 For three months, Sam and I have been stuck here. The last thing we remember was the lights flickering and the plane falling out of the sky. Neither of us knew how we ended up here on this deserted, oddly shaped island surrounded by nothing but the ocean and tall cliffs. 
 
 The island curved in unnatural angles, with strangely placed mountains and lagoons. That's not the most curious thing about the island. As the days went by, we discovered math puzzles hidden all around the island. Etched on tree barks, printed on the rocks, hidden inside the guts of fish were anything from simple algebraic manipulation to second order differential equations. 
 
 In the center of the island was a giant cave. Inside, we found a single ornately-carved table covered with sand. Whenever we wrote the right answer to a math puzzle we found on the table, we were rewarded with food and water. 
 
 Three days ago, we found the final puzzle. All the other puzzles were leading to this one. We discovered that the island was not randomly shaped. They formed exact shapes, letters. They formed the final puzzle. 
 
 *X + 3X – 4 = 0. * That was the question. 
 
 *4X = 4* 
 
 *X = 1* 
 
 One. The answer had to be one. We tried every method to solve the problem. We mapped the entire island a dozen times, checking every inch of ground. We checked our math a hundred times. We had to be right. Except, when Sam went into the cave, he never came out. 
 
 *Do n't worry, Jen, * he'd say. *The two of us will be out of this place in no time. * 
 
 Now, I stand at the top edge of the first'X'. I gaze out at the ocean. Sam and I planned to swim to the island off the coast, right before he disappeared. *I wonder what ’ s on it, * I think to myself. 
 
 Suddenly, it hits me. 
 
 I sprint towards the center of the island, straight into the cave. “ Sam... we got it wrong, ” I mutter to myself, between pants. 
 
 “ The island off the coast. It ’ s the number two. ” 
 
 *X^2 + 3X – 4 = 0. * That was the question. 
 
 * ( X - 1 ) × ( X + 4 ) = 0* 
 
 *X = 1 or X = -4* 
 
 As a quadratic equation, there were two separate solutions. I scratch the numbers one and minus four on the table. Nothing happens. 
 
 Then all of a sudden, the ground shakes and light fills the entire world.
