How do you solve 5q-7=2/3?

5Q - 7 = 2/3

You could begin by adding 7 to each side:

5Q = 7 and 2/3

The rest of it will be a lot easier if you change the right side

to a single fraction. Do you remember how to do that?

7 is the same as 21/3. So 7 and 2/3 is the same as 23/3.

5Q = 23/3

Divide each side by 5:

Q = 23 / (3 x 5) = 23/15 = 1 and 8/15.
