There are 2 ways to do this. I'm going to do it the way that I think is most simple.

You have to find their LCM which is 40. Now times 40 to 1/4     v     and 7/10

The equation then becomes 10+40v=28

You simplify it:     40v=18

v= 9/20

Answer:

v = 9/20

Step-by-step explanation:

1/4 becomes 10/40

7/10 becomes 28/40

28/40 - 10/40 = 18/40

simplify 18/40 divided by 2

v = 9/20
