Answer 1

Respuesta:

Corona pls

Explicación paso a paso:

x + 2 = 6

x + 2 -2 = 6 - 2

x = 4

2 + x - 5 = -x + 3 + 4x

-3 + x = 3x + 3

-3 + x - x = 3x - x + 3

-3 = 2x + 3

-3 - 3 = 2x + 3 - 3

-6/2 = 2x/2

-3 = x

2x + 1 = x + 3

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

x + 1 = 3

x + 1 - 1 = 3 - 1

x = 2

6(x - 1) = -3(2 + x) + 3x + 12

6x - 6 = -6 -3x + 3x + 12

6x - 6 = 6

6x - 6 + 6 = 6 + 6

6x/6 = 12/6

x = 2
