Brother one: x

Brother two: x + 15

---

Make them add up to 55 in an equation.

x + (x + 15) = 55

Combine like terms.

2x + 15 = 55

Subtract 15 from both sides.

2x = 40

Divide both sides by 2.

x = 20

Plug 20 for x into brother two.

(20) + 15 = 35

Brother one has saved $20, brother two has saved $35.
