each person starts with $8.

Step-by-step explanation:

Here we have , Josh had $10 more than Carly, so he gave Carly half of his money. Then Carly had more money than josh, so she gave Josh $4. Then they both had $13. We need to find  How much money did each person start  . Let's find out:

Suppose Carly had $x ,  Josh had $10 more than Carly i.e. $(x+10), so he gave Carly half of his money i.e.

⇒ ,Now , Josh have $  & Carly have .

Then Carly had more money than josh, so she gave Josh $4 . So ,

Josh now have $  and  Carly now have $ . Since both are equal :

⇒  

⇒  

⇒  

Therefore , each person starts with $8.

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
