Question

Lia has $24. Lia and her brother together have a total of $45. The solution of the
equation 24 + x = 45 is the amount of money, x, that Lia's brother has. How much
money does Lia's brother have?

Answer 1

To find out how much money Lia's brother has, we need to solve the equation 24 + x = 45.

Subtract 24 from both sides of the equation:

x = 45 - 24
x = 21

Therefore, Lia's brother has $21.
