Question

Ayuda por favor doy corona​

Answer 1

Explicación paso a paso:

2x + y = 8

2x + y = 8 2x = 8-y

= 8-yx= 8-y /2

2 ( 8 -y /2 ) +y =8

16 -y / 4 +y = 8

-4y +y = 8

-3y = 8

y = -2.66

x= 8 -2.66/2

x= 5.34/2

x= 2.67

___________________________

4x -y = 4

4x -y = 44x = 4 + y

4x -y = 44x = 4 + yx = 4 +y / 4

x= y

4(y) - y = 4

4y - y = 4

3y = 4

y = 4/3

y = 1.33

x=1.33

4x - y = 4

4(1.33) -1.33 = 4

espero te sirva de algo.
