Answer 1

Respuesta:

a. 5x = 25

x = 25/5

x = 5

b. 2x = -234

x = -234/2

x = -117

c. -120 = x(8)

-120/8 = x

x = -15

d. -24x = -96

x = -96/-24

x = 4

e. 68x = -204

x = -204/68

x = -3

f. -5x = -9x - 24

-5x + 9x = -24

4x = -24

x = -6

g. 5 + 2x = 5x -7

2x - 5x = -7 - 5

-3x = -12

-3x = -12

x = -12/-3

x = 4

h. 1 + 4x - 3 = 6x + 8

4x - 2 = 6x + 8

4x - 6x = 8 + 2

-2x = 10

x = 10/-2

x = -5

I. 25x = 120 - 5x + 10x

25x + 5x - 10x = 120

20x = 120

x = 120/20

x = 6

j. 8(x-2) = 4(x+3)

8x - 16 = 4x + 12

8x - 4x = 12 + 16

4x = 28

x = 28/4

x = 7
