Question

ayuden x=6-4y;10x+y=3/2

Answer 1

x = 6 - 4y

10x +y = 3/2
10 ( 6 - 4y) + y=3/2
60 - 40 y+y=3/2
-39y= 3/2 - 60
 y = -117/2  /   -39
y=3/2

x = 6 - 4y
x= 6 - 4(3/2)
x= 6 - 6
x=0

Answer 2

x=6-4y -----    x+4y=6    ......... -20x - 80y= -120
10x+y=3/2 ----  20x+2y= 3


-20x - 80y= -120
  20x+2y= 3
-------------------------
-78y= -117
y= 117/78 se saca 39 ava
y= 3/2
x=6-4y
x= 6 - 4(3/2)
x=  6-6
x=0
