Answer:

The answers are:

a) x = -39/2

b) x = 30

c) x = 5

Explanation:

a) -3/4 = x/26               clear x

    x = -3(26)/4

    x = -78/4 = -39/2     solve

b) x/15 = 20/10             clear x

 x = 20(15)/10             solve

x = 300 /10 = 30

c) x/25 = 3/15                             clear x

  x = 3(25)/15 = 75/15 = 5         solve
