Answer:

Lucy: 10

Daniel: 37

Step-by-step explanation:

Let Daniel's age be d, and Lucy's age be l.

We can set up a system of equations.

d = 7 + 3l

2d-5l = 24

We can subsitute the value of d from the first equation into the second equation.

2*(7+3l)-5l = 24

Distribute:

14 + 6l - 5l = 24

Combine like terms:

l = 10

Plug this value back into the first equation:

d = 7 + 3*10

d = 37
