Question

what should be added to twice the rational number 7/8 to get 3/7​

Answer 1

Answer:

x = -37/28

Step-by-step explanation:

Let number to be added be x.

2(7/8) + x = 3/7

14/8 + x = 3/7

x = 3/7 - 14/8

x = 24-98/56

x = -74/56 = -37/28

Answer 2

Answer:

 

x = -37/28

Step-by-step explanation:

Let number to be added be x.

2(7/8) + x = 3/7

14/8 + x = 3/7

x = 3/7 - 14/8

x = 24-98/56

x = -74/56 = -37/28
