Question

2x+3y=5 4x+y=1 ayúdenme por favor

Answer 1

Respuesta:

X=-1/5

Y=9/5.........,,,

Answer 2

$2x + 3y = 5 \\ 4x + y = 1$

$y = 1 - 4x$

$2x + 3(1 - 4x) = 5$

$2x + 3 - 12x = 5$

$2x - 12x = 5 - 3$

$- 10x = 2$

$x = 2 \div - 10$

$x = - 0.2$

$4( - 0.2) + y = 1$

$( - 0.8) + y = 1 \\ y = 1.8 \\ y = 1.8 \div 1 \\ y = 1.8$

Comprobacion:

$2( - 0.2) + 3(1.8) = 5$

$( - 0.4) + 5.4 = 5$

$5 = 5$
