Hello, can someone provide a step by step process and find the area bounded by the graphs and a graph for question#17 thank you

Questions 15 through 26 refer to the following: Find the area bounded by the graphs of the given equations. Provide a graph of the area in question. 15) y = 6 x, y = [x] 16) y = 2 sin x, y=-3 cos x, x = 0, x = 17) x = y, x+2y= 3
