7x - 3/8 = 6x - 5/8

7x - 6x = 3/8 - 5/8

x = -2/8

x = -1/4

7x - 6x = 3/8 - 5/8

x = -2/8

x = -1/4

3x - 4 = 2x - 10

3x - 2x = 4 - 10

x = -6

3x - 2x = 4 - 10

x = -6

13x + 7 = 5x - 20

13x - 5x = - 20 - 7

8x = - 27

x = -27/8

13x - 5x = - 20 - 7

8x = - 27

x = -27/8

18 - 3n + 2 = n + 20 - 4n

20 - 3n = 20 - 3n

-3n + 3n = 20 - 20

0 = 0

Therefore, the solution set of 18 - 3n + 2 = n + 20 - 4n is all reals

20 - 3n = 20 - 3n

-3n + 3n = 20 - 20

0 = 0

Therefore, the solution set of 18 - 3n + 2 = n + 20 - 4n is all reals

7 + x - 15 = -2 2/3

x - 8 = - 8/3

x = 8 - (8/3) = 24/3 - (8/3) = 16/3

x - 8 = - 8/3

x = 8 - (8/3) = 24/3 - (8/3) = 16/3
