Question

Use Cramer's rule to determine if the system is inconsistent system or contains dependent equations.

2x + 7 = 8
6x + 3y = 24

A. system is inconsistent

B. system contains dependent equations

Answer 1

do you know what Cramer's rule is?? Ever heard of it?

Answer 2

yes i know it but idk how to determine whether its inconsistent or dependent..

Answer 3

Is it 2x + 7 = 8 or
2x + 7y = 8 for the first equation?

Answer 4

it says 7 in the question..

Answer 5

So your equations are
2x + 0y = 1
6x + 3y = 24

x=1/2
3 + 3 y =24
3y = 21
y =7

The system is consistent

Answer 6

so its B?

Answer 7
