Haber, yo te ayudo

Explicación paso a paso:

1. 6 - 2x = x/4 - 3

9 - 2x = x/4

4(9 - 2x) = x

36 - 8x = x

36 = 9x

4 = x

2. 51(3 + b) = 153

153 + 51b = 153

51b = 0

b = 0

3. 15(m – 4) = -60

15m - 60 = -60

15m = -60 +60

15m = 0

m = 0

4. 7 (5 - 3) = 4x – 6

35 - 21 = 4x - 6

14 + 6 = 4x

20 = 4x

5 = x

5. 2x – 8 = ( -6x + 8 ) / 2

2 (2x - 8) = -6x + 8

4x - 16 = -6x + 8

10x = 24

x = 24/10 = 12/5

6. 8(2x – 5) = 4( 1 + 3x )

16x - 40 = 4 + 12x

4x = 44

x = 11

7. 6(6 – 3x) = 4x – 8

36 - 18x = 4x - 8

44 = 22x

2 = x
