### Instruction:
 Antoinette pesa 7 kilogramos menos que el doble del peso de Rupert. Juntos pesan 98 kilogramos. ¿Cuántos kilogramos pesa Antoinette?


### Response:
 Sea x = peso de Rupert
Antoinette = 2x - 7
x + 2x - 7 = 98
3x = 105
x = <<35=35>>35
Antoinette = 2 * 35 - 7 = <<2*35-7=63>>63 kilogramos
Antoinette pesa 63 kilogramos.
