Answer 1

A) (x - 4)/2 + (x + 5)/5 = -1
     5(x - 4)/10 + 2(x + 5)/10 = -1
     5x - 20 + 2x + 10 = -1(10)
     7x - 10 = -10
     7x = -10 + 10
     x = 0/7
     x = 0

b) 2x - 1/2 = 3/2
     2x = 3/2 + 1/2
     2x = 4/2
     2x = 2
       x = 1

c. x/2 = x/7 - 10
    x/2 - x/7 = -10
   7x/14 - 2x/14 = -10
   7x - 2x = -10(14)
   5x = -140
     x = -140/5
     x = -28
