Step-by-step explanation:

Step 1: Define Systems

-24x - 4y = -164

y = 41 - 6x

Step 2: Solve for x

Substitute in y [1st Equation]: -24x - 4(41 - 6x) = -164
[Distributive Property] Distribute -4: -24x - 164 + 24x = -164
[Addition] Combine like terms: -164 = -164

Here we see that -164 does indeed equal -164.

∴ We have an infinite amount of solutions.
