First rewrite it like this
1. y=5/4x
Then, make X the subject
2.4x=5/y
x=(5/y)÷4
3. Once done, simply replace x with h(x)^-1 and y with x
h(x)^-1= (5/x)÷4
Sorry I'm not very good at rearranging formula but hope this helps :)

Rewrite the system of equations in matrix form.

\begin{bmatrix}1&2&-2\\3&7&-1\\2&4&m\end{bmatrix} \mathbf x = \mathbf b

This system has a unique solution \mathbf x = \mathbf A^{-1}\mathbf b so long as the inverse of the coefficient matrix \mathbf A exists. This is the case if the determinant is not zero.

We have

\det(\mathbf A) = m+4

so the inverse, and hence a unique solution to the system of equations, exists as long as m ≠ -4.
