<u>Algebra I</u>

  • Functions
  • Terms/Coefficients
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

-24x - 4y = -164

y = 41 - 6x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in <em>y</em> [1st Equation]:                                                                           -24x - 4(41 - 6x) = -164
  2. [Distributive Property] Distribute -4:                                                                -24x - 164 + 24x = -164
  3. [Addition] Combine like terms:                                                                       -164 = -164

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

∴ We have an infinite amount of solutions.
