The equation is 36 - 4x = 6.
Solution:
To write the equation without fraction.


The denominators must be same to add/subtract the fractions.
LCM of 1, 9 and 3 = 9.
Multiply first term by  and
 and  by
 by  to make the denominator same.
 to make the denominator same.



Multiply by 9 on both sides.

Both 9 in the numerator and denominator get canceled.
36 - 4x = 6
This term does not have fraction.
Hence the equation is 36 - 4x = 6.
