Let's simplify the expression using the properties of logarithms:
log7 x = log7 (14) - log7 (98)
We can rewrite the right side of the equation using the properties of logarithms:
log7 x = log7 (14/98)
Now, simplify the expression inside the logarithm:
log7 x = log7 (1/7)
Since 1/7 is equivalent to 7^-1, we can rewrite the expression as:
log7 x = log7 (7^-1)
Using the property of logarithms where log_a a^b = b, we get:
log7 x = -1
Therefore, the simplified expression is log7 x = -1.
