  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

6x - y = -14

-2x + y = 6

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

<em>Elimination</em>

  1. Combine 2 equations:                    4x = -8
  2. Divide 4 on both sides:                   x = -2

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    -2x + y = 6
  2. Substitute in <em>x</em>:                       -2(-2) + y = 6
  3. Multiply:                                  4 + y = 6
  4. Isolate <em>y</em>:                                 y = 2

Original cost minus the 10% discount
Dmitrij [34]

Hi! I will try my best to answer your question, the wording provided is unclear.

If the 10% of the original cost of something is $1.50, then the total cost is $15.00.

Assuming this is the discounted price, which would be 90% of the original cost, the original cost would be $16.67.
