Are the equations 2x - y = - 4 and 3x + y = -1 dependent, independent or neither

From the above calculations, it is clear that the consistent system has exactly one solution i.e. x = -1, y =2, therefore, it is independent.

Step-by-step explanation:

Given the system of equations

so the system of equations becomes

solving 5y = 10 for y

Divide both sides by 5

simplify

Adding 6 to both sides

Divide both sides by 6

Therefore, the solution to the system of equations be:

From the above calculations, it is clear that the consistent system has exactly one solution i.e. x = -1, y =2, therefore, it is independent.
