Составим систему уравнений:
5х+3у=55,5
3х+5у=54,1
(обозначить систему скобкой { )

Метод сложения:
5х+3у=55,5 (умножим на 3)
3x+5у=54,1 (умножим на 5)

15х+9у=166,5
15x+25y=270,5

_15x+9у=166,5
   15x+25у=270,5
   15х-15х+9у-25у=166,5-270,5
   -16у=-104
   16у=104
у=6,5 центнеров клубники собрали с 1 га.

5х+3у=55,5
5х+3*6,5=55,5
5х+19,5=55,5
5х=55,5-19,5
5х=36
х=36:5
