Final answer:

The value of x - y is -27.

Step-by-step explanation:

To find the value of x - y, we need to determine the values of x and y. We are given that the sum of x and y is 153 and the value of the fraction x/y is 0.7.

From the information given, we can set up a system of equations:

x + y = 153

x/y = 0.7

To solve this system, we can multiply both sides of the second equation by y to eliminate the fraction:

x = 0.7y

Substituting this into the first equation:

0.7y + y = 153

1.7y = 153

y = 90

Plugging the value of y back into the second equation:

x/90 = 0.7

x = 0.7 * 90

x = 63

Finally, we can calculate the value of x - y:

x - y = 63 - 90 = -27
