Transcript text: Find the values of the variables in the equation.
\[
\left[\begin{array}{rr}
s-5 & t+2 \\
-8 & -3
\end{array}\right]=\left[\begin{array}{rr}
8 & 2 \\
-8 & r
\end{array}\right]
\]
\[
\begin{array}{l}
\mathrm{r}=-3 \\
\mathrm{~s}=13 \\
\mathrm{t}=4
\end{array}
\]
Solution
Solution Steps
Step 1: Solve for \(s\)
To find \(s\), we use the equation \(s - a = e\). Substituting the given values, we get \(s - 5 = 8\), which simplifies to \(s = 8 + 5\). Therefore, \(s = 13\).
Step 2: Solve for \(t\)
To find \(t\), we use the equation \(t + b = f\). Substituting the given values, we get \(t - 2 = 2\), which simplifies to \(t = 2 + 2\). Therefore, \(t = 4\).
Step 3: Solve for \(r\)
Since \(r\) is directly given as the element in the second row and second column of the matrix, \(r = d\). Therefore, \(r = -3\).
Final Answer:
The solution to the system of equations is \(s = 13\), \(t = 4\), and \(r = -3\).
