Answer 1

Answer:

-14.85

Step-by-step explanation:

-2(3/7)-(14)

-0.85 - 14

-14.85

we got -0.85 after multiplying -2 with 3/7

Answer 2

Given :

• The value of x is 9/14 and that of y is -3/7.

To Find :

• -2y - x

Solution :

We need to find out the value of -2y-x . On substituting the respective values , we have ,

→ -2 (- 3/7) - 9/14

Simplify ,

→ 6/7 - 9/14

→ (6*2 - 9)/14

→ (12-9)/14

→ 3/14

Hence the required answer is 3/14 .
