Solve this linear system using determinants: 2x + 3y = 6 −8x − 3y = 12 |a| = |ax| =|ay|=

The solution of the system is: and

Explanation

Given linear system is ......

So, the co efficient matrix,

and the answer-column matrix :

Now, we will replace the x and y column in the co efficient matrix by the answer-column matrix for getting and respectively.

So, and

Now, we will find determinant of each matrix. So.....

According to the Cramer's rule,   and

So....

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees
