ayuda por favor​

Answer 1

Respuesta:

la a solo se es 6

a) 2.(3x - 5) = 4x + 8

   2.1 = 4x + 8

   2 = 4x + 8

   2 = 12x

   2 ÷ 12 = x

   6 = x

espero te ayude

Answer 2

                        ECUACIONES

a) 2(3x - 5) = 4x + 8

6x - 10 = 4x + 8

6x - 4x = 8 + 10

2x = 18

x = 9 → RPTA

b) -3(-x + 2) = 2x + 1

3x - 6 = 2x + 1

3x - 2x = 1 + 6

x = 7 → RPTA

c) 2x + 4(x - 2) = 2 + 4x

2x + 4x - 8 = 2 + 4x

6x - 8 = 2 + 4x

6x - 4x = 2 + 8

2x = 10

x = 5 → RPTA

d) 5x - 2(x - 4) = -8 - x

5x - 2x + 8 = -8 - x

3x + 8 = -8 - x

3x + x = -8 - 8

4x = -16

x = -4 → RPTA

e) 6(-1 + x) - 3(2x + 3) = x

-6 + 6x - 6x - 9 = x

-6 - 9 = x

-15 = x → RPTA
