Step-by-step explanation:

$y = 2x - 4$

$3x + y = 1$

$y = 1 - 3x$

Equating,

$2x - 4 = 1 - 3x$

$2x + 3x = 1 + 4$

$5x = 5$

$x = 1$

Placing it,

$y = 1 - 3( 1)$

$y = 1 - 3$

$y = - 2$

Halla el conjunto solución del siguiente sistema de ecuaciones aplicando el método de reducción: 2x + 3y = 8 x – 5y = 6

AysviL [449]

Answer:

x = 7.535 and y = 0.307

Step-by-step explanation:

Given that,

Two equations,

2x + 3y = 8 ...(1)

x – 5y = 6....(2)

Multiply equation (2) by -2.

-2x + 10y = -12....(3)

Now, adding equations (1) and (2),

2x + 3y -2x + 10y = 8-12

13y = 4

y = 0.307

Put the value of y in equation (2).

x – 5(0.307) = 6

x = 6 + 1.535

x = 7.535

So, the solutions of the given equation are x = 7.535 and y = 0.307.
