there are a few ways to solve
(1) turn the mixed numbers into improper fractions 4x3+1 = 13/4 and 2x2+1 = 5/2. from this point you need to make the denominators the same so 2x2=4. whatever you do to the bottom, you must do to the top. so 5x2=10. now your equation is 13/4 + 10/4 from here you just add straight across and leave your denominators as they are. you’ll get 23/4 simplified to 5 3/4 or 5.75
hope this helps!
