Answer:

-13/35

Explanation:

4/5 + x = 3/7

subtract both sides by 4/5

x =
(3)/(7) - (4)/(5)

find the common denominator of 5 and 7

x =
(15)/(35) - (28)/(35)

x = -13/35

Answer:

-13/35

Explanation:

multiply each side of equation by LCD of 5 and 7 (which is 35) to eliminate fractions

you get, 28 + 35x = 15

35x = -13
