a. 13/15
b. - 1/2
c. 1 8/35
d. - 13/35​

Answer 1

Answer:

-13/35

Step-by-step 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

Answer 2

Answer:

-13/35

Step-by-step explanation:

4/5 + x = 3/7

subtract both sides by 4/5

x = $\frac{3}{7} - \frac{4}{5}$

find the common denominator of 5 and 7

x = $\frac{15}{35} - \frac{28}{35}$

x = -13/35
