Your parents are redecorating the dining room and want to place two rectangular wall sconce lights that are inches wide along a / foot wall so that the distance between the lights and the distances from each light to the nearest edge of the wall are all the same. Determine the distance. Let the distance between a light and the nearest edge of a wall be . Write an expression in terms of for the total length of the wall. Then, use the expression and the length of the wall given in the problem to write an equation that can be used to find that distance. Now write an equation where stands for the number of inches: Let the distance between a light and the nearest edge of a wall be inches. Write an expression in terms of for the total length of the wall. Then, use the expression and the length of the wall to write an equation that can be used to find that distance (in inches). What value(s) of makes the second equation true: , , or ?
