a. 7 + 6x + 4 = -8x – 1 + x

b. 3x + 7 – 8x = 5 – x + 7

c. 3x + 7 + x = 6 + 8x + 3

d. 2 – x + 10 = 6x – 3 – 2x

e. -1 + 4x + 1 = -9x – 1 + x

f. 2x + 5 – 3x = -8 – x + 8

a. 3 (2 - x) = 2 + x

b. 2 (3 - 2x) = -4 - 2x

c. 2 (3 - x) = 5x - 8

d. 5 (3 - 2x) = 6 - 5x

e. 2 + 3 (1 - 2x) = 2 (2 + 3x) -3

f. -3(-6x+5) =-3x +9 -2 (8+x)

Answer 1

Respuesta:

a. 6x-8x+1x= 7+4 -1

-1x= 10 + 1

x=11

b. 3x-8x-x = 7+5+7

-6x = 19

x= 19 + 6

x=25

c.3x + x + 8x = 7+6+3

12x= 16

x= 16 - 12

x = 4

d. -x+6x-2x = 2+10-3

3x= 11

x= 11 -3

x= 8

e.4x-9x+x = -1+1-1

-4x= -1

x= -1 + 4

x= 3

f. 2x-3x -x = 5-8+8

-2x = 5

x= 5+2

x = 7
