Question

The difference between -6.4 and a number is 8.5
Find two possible values for the number

Answer 1

Answer:

-14.9 and 2.1

Step-by-step explanation:

it can either be :

1.

x-(-6.4)= 8.5

x+6.4 = 8.5

x = 8.5-6.4

= 2.1

2.

-6.4-x = 8.5

x = -6.4-8.5

= -14.9

Answer 2

Let the number = x

Case I :-

x - (-6.4) = 8.5

x + 6.4 = 8.5

x = 8.5 - 6.4

x = 2.1

Case II :-

-6.4 - x = 8.5

-6.4 - 8.5 = x

x = -14.9

Hence, the two possible values of the number are 2.1 and -14.9
