AYUDENME PORFA DOY CORONITA :(​

Answer 1

Respuesta:

1. Opción

x + y = 3

2x - 2y = 7

2(x+y) = 2(3)

2x-2y = 7

2x + 2y = 6

2x - 2y = 7

4x = 13

x = 13/4

x = 3.25

y = -0.25

2. Opción

x + y = 3

2x - 2y = 1

2(x+y) = 2(3)

2x-2y = 1

2x + 2y = 6

2x - 2y = 1

4x = 7

x = 7/4

x = 1.75

y = 1.25
