Chapter 8 - Section 8.5 - Determinants and Cramer's Rule - Exercise Set - Page 946: 44


$\begin{cases} 2x-3y=8 \\ 5x+6y=11 \end{cases}$

Work Step by Step

Based on the given determinants, recall their definitions and Cramer’s Rule. We can write the system of linear equations as: $\begin{cases} 2x-3y=8 \\ 5x+6y=11 \end{cases}$ Note that we used the first column of $D_{x}$ to find the constants on the right side of the equation and $D$ to find the left side coefficients.
