procedimiento -6+2×-5=5×+10-3
procedimiento 8+12×=15×-19​

Answer 1

Respuesta:

2x + 7 = - 3

2x = -3 - 10

x = -13/2

5x - 7 = x + 9

5x - x = 9 + 7

4x = 16

x = 16/4

x = 4

-9 + 6 x = 9

6x = 9 + 9

6x = 18

x = 18/6

x = 3

5x - 1 = 9

5x = 9 + 1

x = 10/5

x = 2

4x - 2 = 8 + 3x

4x - 3x = 8 + 2

x = 10

-6 + 2x - 5 = 5x + 10 - 3

2x - 5x = 10 - 3 + 6 + 5

-3x = 18

x = 18/-3

x = -6

8 + 12x = 15x - 19

12x - 15x = - 19 - 8

-3x = -27

x = (-27)/ (-3)

x = 9
