David y Almudena tienen entre los dos 225 euros. Calcula cuánto dinero tiene cada uno si Almudena posee 75 euros más que David.
Misha Larkins [42]

David and Almudena have between the two 225 euros. Calculate how much money each has if Almudena has 75 euros more than David.

For this case we propose a system of equations:

x: Let the variable that represents Almudena's amount of money

y: Let the variable that represents David's amount of money

According to the statement we have:

x + y = 225\\y + 75 = x

Substituting the second equation into the first:

y + 75 + y = 225\\2y + 75 = 225\\2y = 225-75\\2y = 150\\y = \frac {150} {2}\\y = 75

We find the value of the variable x:

x = 75 + 75 = 150

Almudena has 150 euros

David has 75 euros

Answer:

Almudena has 150 euros

David has 75 euros
