Question

3× +2y=7 y 4×-3y=-2 porfavor me ayudan a resolver el método de determinantes​

Answer 1

Respuesta:

x = 1

y = 2

Explicación paso a paso:

3× + 2y = 7

4× - 3y = -2

3(3× + 2y = 7) = 9x + 6y = 21

2(4× - 3y = -2) = 8x - 6y = -4

17x = 17

x =1

3× + 2y = 7

3(1) + 2y = 7

3 + 2y = 7

2y = 7 - 3

2y = 4

y = 2
