Nifal earned 9$ for washing two cars .He recived $1 more for the second car.How much was he paid for washing each car?Which two
Sveta_85 [38]

Answer:

Nifal received $ 4 for washing the first car.

Nifal received $ 5 for washing the second car.

4 and 5 have a sum of 9.

Step-by-step explanation:

The problem can be rewritten as follows: Find the sum of two consecutive entire numbers equal to 9. That is:

x + y = 9

y = x+1

Then, by eliminating y:

x + (x+1) = 9

2\cdot x + 1 = 9

Now, let is clear x:

2\cdot x = 8

x = 4

Nifal received $ 4 for washing the first car.

The earning for the second car is: (x = 4)

y = x +1

y = 4 + 1

y = 5

Nifal received $ 5 for washing the second car.

4 and 5 have a sum of 9.
