To solve for x, we can begin by dividing both sides of the equation by 102.5:
(x - 11.92) = 71.6 / 102.5
Simplifying the right side gives:
(x - 11.92) = 0.6985
Now, by adding 11.92 to both sides of the equation, we get:
x = 0.6985 + 11.92
Hence, x is equal to 12.618 when rounded to three decimal places. Therefore, the correct response is: 12.618.
To solve for n, we can begin by dividing both sides of the equation by 50.3:
(n + 9.25) = -120.72 / 50.3
Simplifying the right side gives:
(n + 9.25) = -2.4
Now, by subtracting 9.25 from both sides of the equation, we get:
n = -2.4 - 9.25
Hence, n is equal to -11.65. Therefore, the correct response is: -11.65.
