Josh had $18 and Carly had $8.

Step-by-step explanation:

Given:

Josh had $10 more than Carly.

Josh gave Carly half of his money, then Carly had more money than josh, so she gave Josh $4. Then they both had $13.

Question asked:

How much money did each person start?

Solution:

Let Carly start with money be

Then, Josh start with =

According to question:

For Josh :  

Subtracting both sides by 9,

Multiplying both sides by 2,

Carly start with money be = $8

Josh start with = = 8 + 10 = $18

Therefore, at starting, Josh had $18 and Carly had $8.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
