A washer and dryer cost 1003 combined the washer cost 53 more than dryer what’s the cost of dryer
NeX [460]

Answer:

475

Step-by-step explanation:

Let's call the dryer price is x

Then, the price for the washer is 53 more than the dryer, it would be: x+53

Total price of washer and dryer = 1003

We get the equation:

x+(x+53) = 1003

2x + 53 = 1003

2x + 53 - 53 = 1003 - 53

2x = 950

x = 475

The dryer price is 475

Extra: you can find the cost of the washer by using x+53 = 475+53 = 528

Solve for x 8-2x = 5( x4) ​
MissTica
4/11 because when you multiply 5x4x you get 20x , so 8-2x=20x. Then you move the terms with variables and get -2x-20x=-8. This gives you the answer that -22x=8 and when u divide by 22 to both sides, you get 4/11.
