x+y=60
16x + 20y=11 simplificando 4x + y =11
100 100 25 5
despejamos x en la primera ecuacion
x+y=60...........x=60-y
hacemos sustitucion:
4x + y =11 x=60-y
25 5
4(60-y) + y = 11
25 5
240-4y + y = 11 sacamos mcm
25 5
240-4y + 5(y) = 11(25)
25 5 5 1(25)
240-4y+5y=275
5y-4y=275-240
y=35
si y=35
x=60-y
x=60-35
x=25
hay 25 hombres y 35 mujeres
