Question

x/2 + y/3 = 3
5x +2y = 4x + 10

Answer 1

Respuesta:

Explicación paso a paso:

x/2 + y/3= 3....,.......(1)

5x + 2y= 4x + 10....(2)

Multiplicando (1) por (-6):

(-6)(x/2) (-6)(y/3)= (-6)(3)

-3x - 2y= -18...............(3)

Sumando (2) + (3):

5x-3x+2y-2y= 4x +10-18

2x=4x-8

2x-4x= -8

-2x= -8

x= -8/ -2

x= 4

Sustituyendo x en (1):

4/2 + y/3= 3

2 + y/3= 3

y/3= 3-2

y/3= 1

y= (3)(1)

y= 3
