The statement is false, as the system can have no solutions or infinite solutions.
<h3>
Is the statement true or false?</h3>
The statement says that a system of linear equations with 3 variables and 3 equations has one solution.
If the variables are x, y, and z, then the system can be written as:

Now, the statement is clearly false. Suppose that we have:

Then we have 3 parallel equations. Parallel equations never do intercept, then this system has no solutions.
Then there are systems of 3 variables with 3 equations where there are no solutions, so the statement is false.

It is 1a over bd and 8 over k
It would be 130/7+4 because 130 is the total divide it by how many she does and add how many she already has
Answer:
2160
Step-by-step explanation:
Distance covered per day =540miles
Number of days travelled = 4 days
Therefore,the mil we s travelled altogether= 540×4= 2160
