Worksheet Worksheet 1
1.
Circle and identify the two features that make the equations below make a complete presentation of the mathematical manipulation.
\begin{equation*}
\begin{aligned}
-6x + 16 \amp = -8 \\
-6x \amp = -24 \amp \eqnspacer \amp \text{Subtract $16$ from both sides} \\
x \amp = 4 \amp \amp \text{Divide both sides by $6$}
\end{aligned}
\end{equation*}
2.
Solve the equation \(5x + 9 = 34\) using a complete presentation.
3.
Solve the equation \(4x - 13 = 8\) using a complete presentation.
4.
Work backwards from the given information to derive the original presentation.
\begin{equation*}
\begin{aligned}
\\
\\
\amp \amp \eqnspacer \amp \text{Add $8$ to both sides} \\
\\
x \amp = -3 \amp \amp \text{Divide both sides by $5$}
\end{aligned}
\end{equation*}
