Respuesta :
b + g = 589
b = g + 67
g + 67 + g = 589
2g + 67 = 589
2g = 589 - 67
2g = 522
g = 522/2
g = 261 <=== there are 261 groom's guests
b = g + 67
b = 261 + 67
b = 328 <=== there are 328 bride's guests
b = g + 67
g + 67 + g = 589
2g + 67 = 589
2g = 589 - 67
2g = 522
g = 522/2
g = 261 <=== there are 261 groom's guests
b = g + 67
b = 261 + 67
b = 328 <=== there are 328 bride's guests
