F(3)=16 i saw this problem before so it should be the answer in the end
Let's call the numerator
. Since the denominator is four more than three times the numerator, it means that it equals
. So, the original fraction is

Note that this implies that
, otherwise the denominator would be zero. Now, we need to increase both numerator and denominator by 4, obtaining this new fraction:

Note that this implies that
, otherwise the denominator would be zero. And we know that this equals 925 (assuming that 925925 is some kind of typo/formatting error). This leads to the equation

Since we assumed that the denominator is not zero, we can multiply both sides by it, so that the equation becomes

Subtract 4 from both sides to get

Subtract 2775x from both sides to get

Finally, divide both sides by -2774 to get

62 inches / 175 cm, plus or minus about 2.5 inches (6.5 cm).c
A would be the correct answer
Z = 12.
5z + 8 = 4z + 20
z + 8 = 20
z =12
