Worksheet Worksheet 3
1.
Determine the value of when \(x = 0\text{,}\) \(x = 4\text{,}\) and \(x = -3\text{.}\) Write your results as if-then statements.
2.
Solve \(4x - 3y = 6\) for \(y\) using a complete presentation.
3.
Solve \(ax + by = c\) for \(y\) using a complete presentation.
4.
Work backwards from the given information to derive the original presentation.
\begin{equation*}
\begin{aligned}
\\
\\
\amp \amp \amp \text{Add $c$ to both sides} \\
\\
a \amp = \frac{b + c}{d} \amp \amp \text{Divide both sides by $d$}
\end{aligned}
\end{equation*}
