Both numbers can be divide by 9
5/13
2(3x+3)=3(2x+2)
multiply the first bracket by 2
(2)(3x)=6x
(2)(3)=6
multiply the second bracket by 3
(3)(2x)=6x
(3)(2)=6
6x+6=6x+6
move 6x to the left side
sign changes from +6x to -6x
6x-6x+6=6x-6x+6
0+6=0+6
6=6

Hello! So a mixed number is being subtracted by an improper fraction. To find the difference between the two numbers, we will subtract. It would be set up as 4 5/8 - 3 7/8. First off, because 5/8 is less than 7/8, we add 8/8 to 5/8 and turn 4 into 3. That makes the problem 3 13/8 - 3 7/8. Now, let's subtract. 3 13/8 - 3 7/8 is 6/8 or 3/4 in simplest form. There.
