Encontre o valor de X
Me ajude por favor gente

Answer 1

a) 16x -8 + (+8) = 8x - 10 +8

16x -8 +8 = 8x -2

8x = -2

x = -1/4

b) 16x + (-8x)  = 8x -2 + (-8x)

16x -8x = 8x -2 -8x 
8x = -2

x = -1/4

c) 8*(9x/8) - 8*(8/8)  = 8*(12x/8)  - 8 (10/4)

9x -8 = 12x -20

12x - 9x = 20 -8
3x = 12

x = 4 

d) 3 - (3x -6) = 2x + (4 - x)

3 -3x +6 = 2x +4 -x

-3x + 9 = x +4

x + 3x = 9 - 4

4x = 5

x = 5/4

e) 4*( x - 2 ) = 4 + 2*(x -1)

4x -8 = 4 + 2x -2
4x -2x = 2 + 8
2x = 10

x = 5
