1 & -3 & 2&5 \\
1 &5 &-5&0 \\
3&0&4&7\\
\end{array}\right]$.
Work Step by Step
The given matrix is
The given matrix is
$\left[\begin{array}{ccc|c}
2 & -6 & 4&10 \\
1 &5 &-5&0 \\
3&0&4&7\\
\end{array}\right]$
Perform $ \frac{1}{2}R_1 $.
Multiply row 1 by $\frac{1}{2}$.
$\left[\begin{array}{ccc|c}
2\cdot \frac{1}{2} & -6\cdot \frac{1}{2} & 4\cdot \frac{1}{2}&10\cdot \frac{1}{2} \\
1 &5 &-5&0 \\
3&0&4&7\\
\end{array}\right]$
Simplify.
$\left[\begin{array}{ccc|c}
1 & -3 & 2&5 \\
1 &5 &-5&0 \\
3&0&4&7\\
\end{array}\right]$
