Complete step by step solution:
Now considering from the question we have been asked to solve the given expression $5x+4<39$ .
For doing that we will perform simple basic arithmetic operations like addition, subtraction in between the similar terms in the given expression this will result in a reduced and simplified answer.
We need to perform transformations and siftings also if necessary.
Now as we need expressions for $x$ we need to transfer all other terms except the terms involving $x$ to the right hand side from the right side. After doing that we will have $\begin{align}
  & \Rightarrow 5x<39-4 \\
 & \Rightarrow 5x<35 \\
\end{align}$
Now we will divide both sides of the expression with five. After doing that basic arithmetic division we will have $\Rightarrow x<7$ .

Hence we can conclude that the solution for the given expression $5x+4<39$ is $x<7$.

Note: While answering questions of this type we should be sure with the calculations that we are performing. This is a very simple and easy question and can be answered in a short span of time. We should be careful during performing calculations we can make a mistake and write it as
$\begin{align}
  & \Rightarrow 5x<39-4 \\
 & \Rightarrow 5x<25 \\
 & \Rightarrow x<5 \\
\end{align}$
which is a wrong conclusion.
