3 (x -2) =12
-(4x + 10 ) = 28
-9 x +20 = + 40- 2x
-15x =-30
20x = -30

Answer 1

Respuesta:

Explicación paso a paso:

3(x - 2) = 12

x - 2 = 12/3

x - 2 = 4

x = 4 + 2 = 6

-(4x + 10) = 28

4x + 10 = -28

4x = -28 - 10

4x = -38

x = -38/4 = -19/2

-9x + 20 = 40 - 2x

20 - 40 = - 2x + 9x

-(40 - 20) = 9x - 2x

-20 = 7x

x = -20/7

-15x = -30

x = (-30)/(-15) = 2

20x = -30

x = -30/20 = -3/2

Answer 2

Respuesta:

3(x - 2) = 12

x - 2 = 4

x = 4 + 2 = 6

-(4x + 10) = 28

4x + 10 = -28

4x = -38

x = -38/4 = -19/2

-9x + 20 = 40 - 2x

-20 = 7x

x = -20/7

-15x = -30

x = (-30)/(-15) = 2

20x = -30

x = -30/20 = -3/2

corona por favor xD
