20) x=40

21) x=7

22) x=1

23) x=3

24) x=9

Answer 2

Explicación paso a paso:

48 - 3x = 5x

48 = 5x + 3x

48 = 8x

48/8 = x

6 = x

-4x + 30 = -3x - 10

30 + 10. = -3x + 4x

40. = x

10x - 15 = 4x + 27

10x - 4x = 27 + 15

6x = 42

x = 42/6

x = 7

x - 3( x - 2 ) = 6x - 2

x - 3x + 6. = 6x - 2

6 + 2. = 6x - x + 3x

8. =. 8x

8/8 = x

1 = x

3x + 1 = 6x - 8

1 + 8 = 6x - 3x

9 = 3x

9/3 = x

3. = x

3x - 7 = 2 ( x + 1 )

3x - 7 = 2x + 2

3x - 2x = 2 + 7

x. = 9
