Question

2x + 4y = 200
7x + 3y = 260​

Answer 1

Respuesta:

Explicación paso a paso:

2X + 4Y = 200  

7X + 3Y = 260  

14x+28y=1400

-14x-6y=-520

22y=880

y=40

2x+4*40=200

x=20

(x,y)=(20,40)

Answer 2

Respuesta:

1: x=33.333

2: x= 26

Explicación paso a paso:

1: 2x + 4y = 200

6x = 200

x = 200/6

x=33.333

2: 7x = 3y = 260

10 x = 260

x = 260/10

x= 26
