Respuesta :
x = 2 person tents......y = 4 person tents
x + y = 60........y = 60 - x
2x + 4y = 202
2x + 4(60 - x) = 202
2x + 240 - 4x = 202
2x - 4x = 202 - 240
-2x = -38
x = -38/-2
x = 19 <== u have 19 two person tents
x + y = 60
19 + y = 60
y = 60 - 19
y = 41.....and 41 four person tents
x + y = 60........y = 60 - x
2x + 4y = 202
2x + 4(60 - x) = 202
2x + 240 - 4x = 202
2x - 4x = 202 - 240
-2x = -38
x = -38/-2
x = 19 <== u have 19 two person tents
x + y = 60
19 + y = 60
y = 60 - 19
y = 41.....and 41 four person tents
