How do you sovle 2x+2y=18 6x+y=39

Aleonysh [2.5K]

$\begin{cases} 2x+2y=18 \\ 6x+y=39 \end{cases} \\ \\ W=\left|\begin{array}{ccc}2&2\\6&1\end{array}\right| \ W_{x}=\left|\begin{array}{ccc}18&2\\39&1\end{array}\right| \ W_{y}=\left|\begin{array}{ccc}2&18\\6&39\end{array}\right| \\ \\ W=\left|\begin{array}{ccc}2&2\\6&1\end{array}\right|=2*1-6*2=2-12=-10 \\ \\ W_{x}=\left|\begin{array}{ccc}18&2\\39&1\end{array}\right|=18*1-2*39=-60 \\ \\ W_{y}=\left|\begin{array}{ccc}2&18\\6&39\end{array}\right|=2*39-6*18=-30$

$x= \frac{W_{x}}{W} = \frac{-60}{-10}=6 \\ \\ y= \frac{W_{y}}{W} = \frac{-30}{-10}=3$

To find percent error, you subtract the actual number from your estimate, take the absolute value, and divide by the actual number.

l 96 - 118 l
l -22 l
l 22 l
l 22 l / 118
