Question

Sistema de Ecuaciones
32a+50b=14600
10a+40b=7000

Answer 1

32a+50b=14600

10a+40b=7000

32a=14600-50b

a=14600-50b/32

10a=7000-40b

a=7000-40b/10

14600-50b 7000-40b

-------------------- = ------------------

32 10

10(14600-50b)=32(7000-40b)

146000-500b=224000-1280b

-500b+1280b=224000-146000

780b=78000

b=78000/780

b=100

32a+50(100)=14600

32a+5000=14600

32a=14600-5000

32a=9600

a=9600/32

a=300
