Question

Resolvas as equações baixo:
a) X + 4 -- 3x = 4 + 12 - 3x
b) 5x - 8 + 6 = 2x + 12 - 8 + 6
c) - 4x + 8x + 1 = 13+ 3 + 5
d) X - X - X + 3 + 5 = 28 - X - X - X
e) X - 12 + 2x - 1 = + 11 + 2​

Answer 1

x + 4 - 3x= 4 + 12 - 3x

x - 3x + 3x= 4 + 12 - 4

x= 12

5x - 8 + 6= 2x + 12 - 8 + 6

5x - 2x= 12 - 8 + 6 + 8 - 6

3x= 12

x= 12/3

x= 4

- 4x + 8x + 1= 13 + 3 + 5

- 4x + 8x= 13 + 3 + 5 - 1

4x= 20

x= 20/4

x= 5

x - x - x + 3 + 5= 28 - x - x - x

x - x - x + x + x + x= 28 - 3 - 5

2x= 20

x= 20/2

x= 10

x - 12 + 2x - 1= 11 + 2

x + 2x= 11 + 2 + 12 + 1

3x= 26

x= 26/3
