Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Leonard is 4 years younger than Nina who is half as old as Jerome. If the sum of their ages is 36, what is Leonard's age?

### Response:
 Hebu x iwe umri wa Nina.
Basi, umri wa Leonard ni x - 4.
Na umri wa Jerome ni 2x.
Kwa kuwa jumla ya umri wao ni 36, basi equation ni x + x - 4 + 2x = 36.
Kwa kuchanganya vipengele sawa, equation inakuwa 4x = 40.
Hivyo, thamani ya x ambayo inawakilisha umri wa Nina ni x = 40/4 = <<40/4=10>>10.
Hivyo, Leonard ana umri wa 10 - 4 = <<10-4=6>>6 miaka.
