I am a decimal number having only decimal part with last third decimal digit 3. My tenths place digit is 3 less than my last digit. The digit in hundreds place is 2 times 3. Who am I?

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

=

x=0.8898305 is the answer to that equation
