x + (1)/(7) = (5)/(14)

First, subtract
(1)/(7) from both sides.

x = (5)/(14) - (1)/(7)
Second, find the LCD of the two fraction.
Multiples of 14: 14
Multiples of 7: 7, 14
The LCD is 14.
Third, make the denominators the same as the LCD.

(5)/(14) - (1x2)/(7x2)
Fourth, multiply 1 × 2 to get 2 and 7 × 2 to get 14.

(5)/(14) - (2)/(14)
Fifth, combine the denominators.

(5-2)/(14)
Sixth, subtract 5 - 2 to get 3.

(3)/(14)

Answer as fraction:
(3)/(14)
Answer as decimal: 0.2143
