from the first eqaution y = -2x - 4 so you have 2 expressions in x equal to y so equate these 2 and solve for x

\[\left[\begin{matrix}2 & 1 \\ 3 & -1\end{matrix}\right]\left[\begin{matrix}x \\ y\end{matrix}\right]=\left[\begin{matrix}-4 \\ -2\end{matrix}\right]\] \[A ^{-1}\left[\begin{matrix}\frac{ 1 }{ 5 } & \frac{ 1 }{ 5 } \\ \frac{ 3 }{ 5 } & -\frac{ 2 }{ 5 }\end{matrix}\right]\]\[\left[\begin{matrix}\frac{ 1 }{ 5 } & \frac{ 1 }{ 5 } \\ \frac{ 3 }{ 5 } & -\frac{ 2 }{ 5 }\end{matrix}\right]\left[\begin{matrix}-4 \\ -2\end{matrix}\right]=?\]

\[2x+y=-4\]\[y=3x+2\]you substitute the second equation of y into the first one
anonymous
  • anonymous
so it becomes \[2x+(3x+2)=-4\]
