Solve for \(y\) in \((y=8)\).
Solve for \(y\).
\[(y=8)\]
Remove parentheses.
\[y=8\]
Already solved. No work needed.
\[y=8\]
\[y=8\]
Substitute \(y=8\) into \(by-7=1\).
Start with the original equation.
\[by-7=1\]
Let \(y=8\).
\[b\times 8-7=1\]
Simplify.
\[8b-7=1\]
\[8b-7=1\]
Solve for \(b\) in \(8b-7=1\).
Solve for \(b\).
\[8b-7=1\]
Add \(7\) to both sides.
\[8b=1+7\]
Simplify \(1+7\) to \(8\).
\[8b=8\]
Divide both sides by \(8\).
\[b=1\]
\[b=1\]
Therefore,
\[\begin{aligned}&b=1\\&y=8\end{aligned}\]
b=1;y=8
