1/x = x^-1
sqrt(x) = x^(1\2)
Therefore, answer is:
x^(-1/2)
X + y = 16 (1)
x/y = 3 (2)
-------
x + y = 16
x = 16 - y
1. Substitute x into equation 2
16-y/y = 3
16 - y = 3y
16 = 4y
y = 4
2. Now substitute y into equation 1
x/y = 3
x/4 = 2
x = 12
Therefore, x = 12, y = 4
Lets reduce the equation.
8.35x = 4.25x + 36.90
8.35x - 4.25x = 36.90
4.10x = 36.90
X = 9
