The sum of two rational numbers is -7. if one of the numbers is –15/19, the other number is

Answers

Answer: the other rational number is 118/19

Answer:

-118/19

Step-by-step explanation:

let x, y = the two rational numbers, respectively.

What do we know?

  • x + y = -7
  • x = -15/19

Step one: Plug in the values:

-15/19 + y =-7

Step two: Isolate the variable by adding 15/19 on both sides

y = -7 +15/19

Step three: Simplify the right side

Use basic addition to add the two numbers:

y = - 118/19
