Worksheet Worksheet 5
1.
Solve the equation \((x - 5) + a = b\) for the expression \((x - 5)\text{.}\)
2.
Solve the equation \(3 (y + 3) + a = b\) for the expression \((y + 3)\text{.}\)
3.
Work backwards from the given information to derive the original presentation.
\begin{equation*}
\begin{aligned}
\\
\\
\amp \amp \amp \text{Add 4 to both sides} \\
\\
\amp \amp \amp \text{Divide both sides by 6} \\
\\
\amp \amp \amp \text{Rewrite the fraction} \\
\\
a \amp = \frac{b}{6} + \frac{2}{3} \amp \amp \text{Reduce}
\end{aligned}
\end{equation*}
