Question

eu buguei mas é facil 10-(8x-2)=5x+2(-4x+1)

Answer 1

Olá,

vamos lá,

10-(8x-2)=5x+2(-4x+1)
10 - 8x + 2 = 5x -8x + 2
- 8x + 8x - 5x = 2 - 2 - 10

- 5x = -10

5x = 10

x = 10/5

x = 2

Answer 2

10 - (8x - 2)  = 5x + 2(-4x +1)

10 - 8x +2  = 5x -8x +2
-8x -5x +8x = 2 -10 -2
-5x = -10 (-1)
5x = 10
x = 10/5 =           x=2
