2x + 5 = 9
3x + 7 = 2x - 4
8x - 90 = 3x
4x - 10 = 6x + 8
2 . (3x - 2) = 8

Answer 1

Respuesta:

x=2

x=-11

x=18

x=-9

x=2

Explicación paso a paso:

2x=4

x=2

3x-2x=-4-7

x=-11

5x=90

x=18

-10-8=6x-4x

-18=2x

-9=x

6x-4=8

6x=12

x=2

Answer 2

respuesta .

$2x + 5 = 9$

2X = 9 - 5

2X = 4

X = 4 ÷ 2

X = 2

$3x + 7 = 2x - 4$

3x - 2x = - 4 -7

1x = - 11

x= - 11 ÷ 1

x = - 11

$8x - 90 = 3x$

8x - 3x = 90

5x = 90

x= 90 ÷ 5

x= 18

$4x - 10 = 6x + 8$

4x- 6x = + 8 + 10

-2x = 18

x= -18/2

x= - 9

$2.(3x - 2) = 8$

6x - 4= 8

6x = 8+4

6x = 12

x= 12 ÷6

x = 2
