Julio has 5 more dollars than Dan. Altogether, Julio and Dan have 19 dollars. How much money does each young man have?
6. Let d represent the amount of money, in dollars, that Dan has. Use d to write an expression that represents the amount of money that Julio has.​

Respuesta :

First, let's declare our variables

d = Dan's money

d + 5 = Julio's money

Let's create an equation to model the problem.

d + d+5 = 19

Simplify the left side.

2d + 5 = 19

Subtract 5 from both sides.

2d = 14

Divide both sides by 2.

d = 7.

Let's plug 7 into our expression to get Julio's money.

d+5 = (7) + 5 = 12

Dan has $7 and Julio has $12
