You are now equipped with the skill to manipulate and simplify algebraic expressions from \textsc{Lessons 1 and 4}. As such, today we are going to practise the skill of converting real life problems into algebraic ones and then solving these problems mathematically.

Let us immediately begin with 2 examples to gauge the flavour of today's lesson:

\begin{examplebox}
    \subsection{Examples:}
    \begin{questions}
        \questionpoints[1] Fiona is 5 cm taller than Tristan. Tristan's height is $h$ cm. What is Fiona's height?
        \begin{solutionordottedlines}[2cm]
        \end{solutionordottedlines}
        \questionpoints[1] Seuret weighs 2 kg less than his older sister Vivian. If Vivian weighs $w$ kg, what is Seuret's weight?
        \begin{solutionordottedlines}[2cm]
        \end{solutionordottedlines}
    \end{questions}
\end{examplebox}
