Without graphing, classify each system as independent, dependent, or inconsistent. { -1-y=7, 5x-5y =5

In standard form, your equations are

These equations are independent.

_____

Many forms of solution of linear equations are simpler when starting from standard form. For the purpose here, that form helps you see whether the coefficients are multiples of each other (they're not), which would indicate the system is dependent or inconsistent.
