x/5 - x/6 = 1
(6x - 5x)/30 = 1
x/30 = 1
x = 30

(x / 5) - (x / 6) = 1
Multiply both sides of the equation by 30 (LCD)
6x - 5x = 30
x = 30
To check, substitute the value of x into the equation:
(x / 5) - (x / 6) = 1
30/5 - 30/6 = 1
6 - 5 = 1

Solve,
(x / 5) - (x / 6) = 1
Multiply throughout by 30
6x - 5x = 30
x = 30

x/5 -x/6=1
Multiplying both sides by 30,the LCM of 5 and 6,we get
30x/5 -30x/6=1*30
6x-5x=30
x=30 ans

x=30, arrived at as follows:
multiply by least common denominator (30)
thus: 30(x/5) -30 (x/6)=1
simplify: 30x/5 -30x/6=30
solve: 6x-5x=30
solve: x=30

multiply the first term by 6/6 and the second by 5/5.
your new equation will be
(6x/30) - (5x/30) = 1 OR (6x - 5x) / 30 = 1
solve for x

get a common denominator:
6x/30 - 5x/30 = 1
add the fractions
x / 30 = 1
multiply the 30 to the otherside
x = 30

(x/5)-(x/6)=1
6(x/5)-5(x/6)=30(1)
6x-5x=30
x=30
