Is that the floor function?

If so then x = 42 2/7

floor(42 2/7) = 42
42 * 42 2/7 = 1776

The way to get there is to take the sqrt(1776) and round down to the nearest integer. Then divide this into 1776 to get your result.

Alternatively, if you meant that to be the absolute value function |x| then the answer is x = sqrt(1776) ≈ 42.142615

Xx(X) = X*2
X*2 =1776
X=the square root of 1776
X=42.14
