Answer:
3/5x+3/8
Step-by-step explanation:
Start by adding the x values together. This is easy because they have the same base (5). Since one is 2/5 and the other is 1/5, the sum is 3/5. This next part with the x-free fractions is fairly easy, if you recognize that 5/8 and -1/4 can be changed so that they have the same base. Simply multiply both the numerator and denominator of -1/4 by 2, which gives you -2/8. Then subtract this from 5/8, and get 3/8.
Hope this helped :)
