It says to solve the system of linear equations. and tell if they are independent, dependent, or inconsistent.

Do you know what independent, dependent or inconsistent means in terms or linear equations?
Independent
take this example: y=x+10
y=2x
to be independent, the lines must cross at a single point, which in this case they do.
The solutions to y and x must also be numbers, in this case x=10, y=20, whenever you get an answer involving one of the variables, then the equations are independent.
Dependent
take this example: y=x+10
2y=2x+20
to be dependent, the lines are exactly the same, and are 'on top' of each other. When you try to solve this, you will get 0=0, the rule of thumb is, when you get something that is true (could be 5=5 or 2=2 etc) then the equations are dependent.
Inconsistent
take this example: y=x
y=x+10
to be inconsistent, the two lines must never cross this these. When you try to solve this you will get something that is not true like 0=10, the rule of thumb is, whenever you get something that is not true, then the equations are inconsistent.
