Final Answer: The solution to the equation is $x=\boxed{-2}$.

Steps

Step 1 ：We are given a linear function $f(x)=5x+4$ and we are asked to find the value of $x$ when $f(x)=-6$. This is a simple algebraic problem where we need to substitute $f(x)$ with $-6$ and solve for $x$.

Step 2 ：Substitute $f(x)$ with $-6$ in the equation, we get $5x + 4 = -6$.

Step 3 ：Solving this equation for $x$, we get $x=-2$.

Step 4 ：Final Answer: The solution to the equation is $x=\boxed{-2}$.
