# Determine cot 2x if cot x = 1/3.
sciencesolve | Certified Educator
You also may use the following trigonometric identities, such that:
`cot 2x = (cos 2x)/(sin 2x)`
`1 + cot^2 x = 1/sin^2 x`
The problem provides the value of `cot x` , such that:
`1 + (1/3)^2 = 1/sin^2 x => 10/9 = 1/sin^2 x => sin^2 x = 9/10`

# How do you solve the simultaneous equations 4x + y = 9 and 2x - y = 3?
Jul 13, 2015
Since both given equations contain similar coefficients for $y$, the simplest method is to add the two equations and solving single variable equations to get
$\left(x , y\right) = \left(2 , 1\right)$
