Step-by-step explanation:

(-5/7)+x = 13/21, or

(-5/7)+x = 13/21, or-15 + 21x = 13, or

(-5/7)+x = 13/21, or-15 + 21x = 13, or21x = 28, or

(-5/7)+x = 13/21, or-15 + 21x = 13, or21x = 28, orx = 28/21 or 4/3.

(-5/7)+x = 13/21, or-15 + 21x = 13, or21x = 28, orx = 28/21 or 4/3.So add 4/3 to (-5/7) to get 13/21.

(-5/7)+x = 13/21, or-15 + 21x = 13, or21x = 28, orx = 28/21 or 4/3.So add 4/3 to (-5/7) to get 13/21.Check: 4/3 +(-5/7) = (28–15)/21 = 13/21. Correct.
