please help me with this homework problem

Write the system in the form \( A X=B \). Use \( X=A^{-1} B \) to solve the system for each matrix \( B \). \[ \begin{array}{l} \left.\begin{array}{l} 7 x_{1}-2 x_{2}=b_{1} \\ 3 x_{1}-2 x_{2}=b_{2}, \end{array}\right)\left(\begin{array}{l} 6 \\ 3 \end{array}\right), \quad \mathbf{B}=\left(\begin{array}{l} 10 \\ 90 \end{array}\right), \quad \mathbf{B}=\left(\begin{array}{r} 0 \\ -60 \end{array}\right) \\ \mathbf{x}=\left(\begin{array}{l} \left.\mathbf{B}=\left(\begin{array}{l} 6 \\ 3 \end{array}\right)\right) \end{array}\right)\left(\mathbf{B}=\left(\begin{array}{l} 10 \\ 90 \end{array}\right)\right) \\ \mathbf{X}=\left(\begin{array}{r} 0 \end{array}\right) \\ \left.\mathbf{X}=\left(\begin{array}{r} -60 \end{array}\right)\right) \end{array} \]
