Step-by-step explanation:

<u>Step 1: Define</u>

-3y + 14 + y = 12

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

  1. Combine like terms [Addition]:                                                                        -2y + 14 = 12
  2. [Subtraction Property of Equality] Subtract 14 on both sides:                       -2y = -2
  3. [Division Property of Equality] Divide -2 on both sides:                                y = 1

Joe decides to take his six year old son to the planetarium. The price for the child's ticket is 5.75 dollars less than the pric
mart [117]
To answer this item, we are instructed that the price of the ticket for the children is equal to x. Since, we are also given that this is 5.75 less than the price of tickets for the adults, we may express this as follows,

    x = n - 5.75

n is the price of ticket for the adults. This can be calculated by transposing 5.75 to the other side of the equation,

   n = x + 5.75

The answer is the third choice.
