Respuesta:Las ecuaciones :
32A + 50B= 14600
10A+ 40B= 7000
Metodo sustitución.
32A + 50B= 14600
32A= 14600 - 50B
A= (14600 - 50B)/32
Sustituimos en la otra ecuacion
10A+ 40B= 7000
10(14600 - 50B)/32.+40B = 7000
(146000 - 500B)/32+40B= 7000
146000 -500B +1280B = 224000
780B = 224000 - 146000
780B= 78.000
B= 78000/780
B= 100
A= (14600 - 50B)/32
A= (14600 - 50(100))/32
A= (14600- 5000)/32
A= 9.600/32
A= 300
Los asientos A valen 300 y los B valen 100
