Write an equation to solve this problem:

Two brothers are saving money to but tickets to a concert. Their combined savings is $55. One brother has $15 more than the other. How much has he saved?

The answer to your question is: One has saved $35 and the other $20

Step-by-step explanation:

Data

2 brothers

combined savings = $55

One brother has $15 more than the other

x = savings of one brother

y = savings of the other brother

- Process

Write an equation or two equations and solve it for x and y

(1) x + y = 55

(2) x = y + 15 Solve this system by substitution (2) in (1)

y + 15 + y = 55

2y = 55 - 15

2y = 40

y = 40/2

y = $ 20

x = 20 + 15

x = $ 35
