Question

3x-2y=-16
5x+3y=8
metodo de igualacion

Answer 1

Respuesta:

Explicación paso a paso

3x - 2y = -16...e1

5x + 3y = 8....e2

De e1:

3x -2y = -16

3x = -16 + 2y

X = (-16+2y)/3 .......e3

De e2:

5x +3y =8

5x = 8 - 3y

X = (8-3y)/5......e4

Igualamos e3 y e4

(-16+2y)/3 = (8-3y)/5

5(-16+2y) = 3(8-3y)

-90+10y = 24 - 9y

10y + 9y = 24 + 90

19y = 114

Y= 114/19

Y= 6

Reemplazo y en e3

X= (-16+2y)/3

X= (-16+2(6))/3

X= (-16+12)/3

X=(-4)/3
