Flying with the wind, a plane went 366 mph. Flying into the same wind, the plane only went 350 mph. Find the speed of the wind and the speed of the plane in still air.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
