Answer 1

p) 5.(3x - 2) = 2.(6x + 3)

   15x - 10 = 12x + 6

   15x - 12x = 10 + 6

   3x = 16

   x = 16/3

q) 2.(3x-1) + 2.(3-x)=0

   6x - 2  + 6 - 2x = 0

   4x + 4  = 0

   x = -1

r) 7.(x-1) = 2.(3x+1)

 7x - 7 = 6x + 2

 7x - 6x = 2 + 7

 x = 9

s) 2.(3 - y) + 7.(2- y) = 15 - 4y

   6 - 2y + 14 - 7y = 15 - 4y

   9y - 4y = 20 - 15

   5y = 5

   y = 1

t) 2.(x-2) + 5.(2-x) + 6.(x + 1)= 0

  2x - 4 + 10 - 5x + 6x + 6 = 0

  3x = -12

  x = -4

u) 3. (x - 2) - (1 - x) = 13

   3x - 6 -1 + x = 13

   4x = 13 + 7 = 20

   x = 5

v) x - (x + 1) = 12 - (3x - 2)

   -1 = 12 - 3x + 2

   3x = 14 + 1 = 15

   x = 5
