alguien puede resolver esto porfis

Answer 1

Explicación paso a paso:

a)

{x - 3y = 2

{-x + 5y = 2

{x = 2 + 3y

{-x + 5y = 2

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

y = 2

x = 2 + 3 × 2

x = 8

(x, y) = (8, 2)

Comprobación...

{8 - 3 × 2 = 2

{-8 + 5 × 2 = 2

{2 = 2

{2 = 2{2 = 2

b)

{x/2 - y/3 = 2

{-x + y/2 = - 9/2

{x/2 - y/3 = 2

{x = 9 + y/2

9 + y/2/2 - y/3 = 2

y = 3

x = 9 + 3/2

x = 6

(x, y) = (6, 3)

Comprobación...

{6/2 - 3/3 = 2

{-6 + 3/2 = - 9/2

{2 = 2

{2 = 2{- 9/2 = - 9/2
