Two brothers are saving money to buy tickets to a concert. their combined saving is $55 one brother has $15 more than the other.
Vladimir [108]

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

x = 20

Plug 20 for x into brother two.

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