Solve each system using a matrix
Serjik [45]

<u>ANSWER </u>


x=\frac{1}{2} and y=\frac{1}{4}



<u>EXPLANATION</u>


Given;

4x-12y=1

and

6x+4y=4

The augmented matrix of the two linear equation is given by;


\left[\begin{array}{ccc}4&-12|&-1\\6\:&\:\:\:4|&4\end{array}\right]


We now perform row operations;

\frac{1}{4}\times R_1 \rightarrow R_1.

This gives us


\left[\begin{array}{ccc}1&-3|&\frac{-1}{4}\\6\:&\:\:\:4|&4\end{array}\right]



R_2-6R_1 \rightarrow R_2


\left[\begin{array}{ccc}1&-3|&\frac{-1}{4}\\0\:&\:\:\:22|&\frac{11}{2}\end{array}\right]


\frac{1}{22}R _2 \rightarrow R_2


\left[\begin{array}{ccc}1&-3|&\frac{-1}{4}\\0\:&\:\:\:1|&\frac{1}{4}\end{array}\right]


R_1+3R_2 \rightarrow R_1


\left[\begin{array}{ccc}1&0|&\frac{1}{2}\\0\:&\:\:\:1|&\frac{1}{4}\end{array}\right]


Hence x=\frac{1}{2} and y=\frac{1}{4}
