3/5 : x = 1/3 + 12

3/5 : x = 37/3

x = 3/5 : 37/3

x = 9/185.

Vậy x = 9/185.

x : 7/11 = 2

x = 2 xx 7/11

x = 14/11

Vậy x = 14/11.

x – 3/2 = 11/4 – 54

x – 3/2 = -205/4

x = -205/4 + 3/2

x = -199/4.

Vậy x = -199/4.

x + 5/4 = 3/2 + 7/12

x + 5/4 = 25/12

x = 25/12 – 5/4

x = 5/6.

Vậy x = 5/6.

x + 5/4 = 1427/2

x = 1427/2 – 5/4

x = 2849/4
