b.     3. (3x+6) – 2= 4.(2x-3)

c.       4 x – 3 (2x – 1) = 6 – (x – 1)
 
d.      2 (3x -1) – (x + 2) = 4 ( x+1)
​

Answer 1

Respuesta:

Explicación paso a paso:

4x - 2x + 3= 5. (2x-9)

a)6

3. (3x+6) – 2= 4.(2x-3)

b)$\frac{16}{5}$

4 x – 3 (2x – 1) = 6 – (x – 1)

c)-4

2 (3x -1) – (x + 2) = 4 ( x+1)

d)8

Answer 2

a) 4x - 2x + 3 = 5 (2x-9)

   2x + 3 = 10x -45

   48 = 8x

   x = 6

b) 3 (3x+6) - 2 = 4 (2x-3)

   9x + 18 - 2 = 8x - 12

   9x - 8x = - 12 - 18 + 2

   x = -28

c) 4x - 3 (2x-1) = 6 - (x - 1)

   4x - 6x + 3 = 6 - x + 1

   -2x + x = 6 + 1 -3

   -x = 4

    x = -4

d) 2 (3x-1) - (x+2) = 4 (x+1)

   6x - 2 - x - 2 = 4x + 4

   5x - 4x = 4 + 2 + 2

   x = 8
