To solve for x in each equation, we can isolate the variable by multiplying both sides by the reciprocal of the coefficient of x.

1) 25/27 x = 5/18
x = (5/18) (27/25)
x = 1/6

2) 13/17 x = 39
x = 39 (17/13)
x = 51

3) 4x = 5/7
x = (5/7) * (1/4)
x = 5/28

Therefore, the solutions for x in each equation are:
x = 1/6
x = 51
x = 5/28
