Question

What is the value of the system determinant for the following system of equations?

6x + y = 4

5x + y - 7 = 0

Answer 1

-1
1
31 are the answer choices

Answer 2

6x +y =4
5x+y-7 =0 Move -7 to the right side of "="

6x +y =4
5x +y =7 Now put it to your calculator. mine is casio fx-115ES

If you use the same calculator as mine, u r lucky. Chose mode > 5 > 1 into EQN mode
put in 6, 1, 4, 5, 1, 7. then you will have an answer as x= -3, y=22
Test it by plug it into your question and see if they are right

Answer 3

What is the value of the system determinant for the following system of equations?
6x + y = 4
5x + y - 7 = 0 or 5x+y=7.

The determinant for this system of equations is 6*1-5*1=1.

I hope the above steps were helpful.
