No, that is not the reason. Look at the final row; it is shorthand for an equation involving x1, x2, x3, x4, x5. What is the equation?
I have attached the question
The Attempt at a Solution
I think the answer is no solution because there is 5 variables but only 3 equations. Is that correct?
For what values of the variables x1, x1, x2, x3, and x4 will this be a true statement?do you mean 0x1 + 0x2 + 0x3 + 0x4 + 0x5 = 4?
Not necessarily. There are three possibilities for a system of equations (which are here represented by an augmented matrix):if the third is also an equation that means there must be an answer right?
So because we have to assign variables and we have 5unknowns and 3 equations that must mean two values will be variables right?? so the answer has to be B yeah??
