Question

3×(4x-1)+9-4×(x+1)=4x b) 3x-3/2=3/2x. c)1/6-x/2=-2x/3+1/4= ajuda por favor​

Answer 1

Resposta:

12X - 3 + 9 - 4x - 4 = 4x

12x +2-4x= 4x

12x - 4x - 4x = -2

12x - 8x = - 2

4x = - 2

x = - 2 /4

x = - 1/2

b) 3x - 3/2 = 3/2x

3x - 3/2 x = 3/2

6x/2 - 3x/2 = 3/2

3x/2 = 3/2

x= 2 . 3/ 3.2

x= 6/6 = 1

c) 1/6 - x/2 = -2x/3 + 1/4

2/12 - 6x/12 = -8x/12 + 3/12

-6x/12 + 8x/12 = 3/12 - 2/12

- 2x/12 = 1/12

-2x = 1

x= - 1/2
