Answer 1

Step-by-step explanation:

Q1. x/2 + 2x/3 + 3x/4 = 5/6

LCM of 2, 3 and 4 is 12.

6x/12 + 8x/12 + 9x/12 = 5/6

6x + 8x + 9x/12 = 5/6

23x/12 = 5/6

23x = 5/6 x 12

23x = 5x2

23x = 10

x = 10/23

Q2. 5 - (x - 1/2) + 5/6 = 3x/12

5 - x + 1/2 + 5/6 = x/4

5 - 1/2 + 5/6 = x/4 + x

30/6 - 3/6 + 5/6 = x + 4x/4

30-3+5/6 = 5x/4

28/6 = 5x/4

14/3 = 5x/4

14 x 4 = 5x x 3

56 = 15x

56/15 = x

Q3. x+5/6 - 3-x/2 = 5x - 2/12

x+5/6 - 9 - 3x/6 = 5x - 2/12

x + 5 - 9 - 3x/6 = 5x - 2/12

-2x - 4/6 = 5x - 2/12

-x - 2/3 = 5x - 2/12

12(-x - 2) = 3(5x - 2)

-12x - 24 = 15x - 2

-12x - 15x = - 2 + 24

-27x = 12

x = 12/-27

x = 4/-9
