The Eastons traveled 180 miles on a trip to Grandma’s house. At the end of the trip the odometer read 8,246 miles. Write and solve an equation to find the odometer reading x at the beginning of the trip. x – 180 = 8,246; 8,066 miles x + 180 = 8,246; 8,426 miles x – 8,246 = 180; 8,426 miles x + 180 = 8,246; 8,066 miles I dont understand what its saying for me to do plz help!!!
