The total area of the garden and path is 551 in². The area of the garden alone is 15 in * 25 in = 375 in². The area of the path is 551 in² - 375 in² = 176 in². Let x be the width of the path. The dimensions of the garden plus path are (15 + 2x) by (25 + 2x). The equation is (15 + 2x)(25 + 2x) = 551. Solving for x gives x = 2 in.
