4:5x - 3(3:4)x = 2(1:2)

4/5x - 3(3/4)x = 2(1/2)

4/5x - 9/4x = 1

multiply 20 on both sides;

16x - 45x = 20

-29x = 20

x = -20/29

4/5x - 3(3/4)x = 2(1/2)

4/5x - 9/4x = 1

multiply 20 on both sides;

16x - 45x = 20

-29x = 20

x = -20/29

3:7 - 4:m

= 3/7 - 4/m

= 3m/7m - 28/7m

= (3m - 28)/7m

= 3/7 - 4/m

= 3m/7m - 28/7m

= (3m - 28)/7m
