Question

Write an equation to solve this problem:

Answer 1

Answer:

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
