Let x be the length of one part; then the length of the other part is (100-x).


Next, write the equation from the condition


     -  = 18.


Multiply by 3*4 = 12 both sides


    3*(100-x) - 4x = 12*18.


Simplify


    300 - 3x - 4x = 216 - 300

    -7x = -84

     x =  = 12.


ANSWER.  The parts are 12 and 100-12 = 88.


CHECK.   -  = 22 - 4 = 18.    ! Correct !

Solved.
