Explicación paso a paso:

3x+2y = 8

2y = 8

X - 8 - 3x = 0

-8 -0 = 3x - X

-8 = 2x

-8 ÷ 2 = X

-4 = X

3x+2y=8

3x+2y=8 2y = 8 - 3 ( -4 )

3x+2y=8 2y = 8 - 3 ( -4 ) 2y = 8 + 12

3x+2y=8 2y = 8 - 3 ( -4 ) 2y = 8 + 12 2y = 20

3x+2y=8 2y = 8 - 3 ( -4 ) 2y = 8 + 12 2y = 20 y = 20 ÷ 2

3x+2y=8 2y = 8 - 3 ( -4 ) 2y = 8 + 12 2y = 20 y = 20 ÷ 2 y = 10

3x+2y=8 2y = 8 - 3 ( -4 ) 2y = 8 + 12 2y = 20 y = 20 ÷ 2 y = 10

-2x+3y=-1

5x-3y=7

-2x+3y=-1

3y = -1 + 2x

5x-3y=7

5x - ( -1 + 2x ) = 7

5x + 1 - 2x = 7

5x - 2x = 7 - 1

3x = 6

X = 6 ÷ 3

X = 2

-2x+3y=-1

-2x+3y=-1 3y = -1 + 2x

-2x+3y=-1 3y = -1 + 2x 3y = -1 + 2 ( 2 )

3y = -1 + 4

3y = 3

y = 3 ÷ 3

y = 1
