Question

problema de igualación 2x+3y=-1. 3x+4y=0​

Answer 1

Respuesta:

2x + 3y = 1

3x + 4y = 0

Explicación paso a paso:

2x = 1 - 3y

x = (1 - 3y)/2

3((1 - 3y)/2) + 4y = 0

(3 - 9y)/2 + 4y = 0

((3 - 9y) + 8y)/2 = 0

3 - 9y + 8y = 0

3 = y

Reemplazamos:

2x + 3y = 1

2x + 3(3) = 1

2x = 1 - 9

2x = -8

x = -4

Comprobamos:

● 2x + 3y = 1

2(-4) + 3(3) = 1

-8 + 9 = 1

● 3x + 4y = 0

3(-4) + 4(3) = 0
