Explanation Given: The bar graph showing the deaths in 20 th century is shown below Explanation: Consider that the number of deaths in 20 th century due to war, famine, and tobacco is x, y, and z millions respectively. The number of deaths combing war, famine, and tobacco is 306 million, hence the equation becomes: x + y + z = 306 The difference between number of deaths between war and famine is 13 million, hence the equation becomes: x − y = 13 The difference between number of deaths between war and tobacco is 53 million, hence the equation becomes: x − z = 53 From the equation x − y = 13 , y = x − 13 From the equation x − z = 53 , z = x − 53 Substitute the value of y and z in equation x + <
