Question

ayuda son ecuaciones de primer grado, son para mañana, y el que no conteste es gey ;v (que conteste bien) y le doy 5 estrellas
$2x - 3 = 6 + x$
$2(2x - 3) = 6 + x$
$4x + 6x = 20$
$2x - 4x = 30$
​

Answer 1

Explicación paso a paso:

(2)

2x - 3 = 6 + x

2x - x = 6 + 3

x = 9

(3)

2(2x - 3) = 6 + x

4x - 6 = 6 + x

4x - x = 6 + 6

3x = 12

x = 12/3

x = 4

(4)

4x + 6x = 20

10x = 20

x = 20/10

x = 2

(5)

2x - 4x = 30

-2x = 30 //(-1)

2x = -30

x= -30/2

x = -15

(espero te sirva ;;)

Answer 2

2x - 3 = 6 + x

2x - x = 6 + 3

x = 9

2(2x - 3) = 6 + x

4x - 6 = 6 + x

4x - x = 6 + 6

3x = 12

x = 12/3

x = 4

4x + 6x = 20

10x = 20

x = 20/10

x = 2

2x - 4x = 30

-2x = 30 //(-1)

2x = -30

x= -30/2

x = -15
