Question

-5x+3y=-3
3x+4y=2
Porfavor me ayudan con este problema​

Answer 1

Respuesta:

-5x + 3y = -3 -5(0.62) + 3(0.034) = -3 -3 = -3

3x + 4y = 2 3(0.62) + 4(0.034) = 2 2 = 2

x = 0.62 y = 0.034

Explicación paso a paso:

x= -3 -3y / -5

x= 2 -4y / 3

-3 -3y / -5 = 2 -4y /3

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

-9 - 9y = -10 + 20y

-9y -20y = -10+9

-29y = -1

y = -1 / -29

y = 0.034

‐---‐-----------------------

-5x + 3y = -3

-5x = -3 - 3(0.034)

-5x = -3 -0.102

-5x = -3.102

x = -3.102 / -5

x=0.62

3x +4y = 2

3x = 2 -4(0.034)

3x = 2 -0.136

3x = 1.864

x = 1.864 / 3

x = 0.62

---------------------------

-5x + 3y = -3 -5(0.62) + 3(0.034) = -3 -3 = -3

3x + 4y = 2 3(0.62) + 4(0.034) = 2 2 = 2
