5x/7 - 6x/5 = 3/35
The LCD of 7 and 5 is 35.
Multiply the equation by 35.
25x - 42x = 3
-17x = 3
x = 3/(-17)

Our equation is 5x/7-6x/5=3/35.
We have to find the value of x.
LCM of 7 and 5 is 7*5 = 35.
5x /7 = (5x / 7) *(5/5) = 25x / 35
6x / 5 = (6x / 5)* (7/7)= 42x / 35
So, 5x/7 - 6x/5 = 25x/35 - 42x/35 = (25x- 42x)/ 35 = -17x/35
So, -17x/35 = 3/35
That is, -17x = 3.
That is, x = -3/17
