Question

Sistema de ecuaciones
$5x - 3y = 11 \\ 4x + y = 2$
​

Answer 1

Explicación paso a paso:

5x - 3y = 11

4x + y = 2

y = 2 - 4x

5x - 3y ( 2 - 4x) = 11

5x - 6y + 12x = 11

5x +12x = 11 + 6

17x = 17

X = 17/17

X = 1

4x + y = 2

4* 1 + y = 2

4 + y = 2

Y = 2 - 4

Y - 2

Comprobación

5x - 3y = 11

5*1 - 3*-2 = 11

5 +6 = 11

11 = 11 //✔️✔️

4x + y = 2

4*1 + (-2) = 2

4 - 2 = 2

2 = 2 // ✔️✔️
