Step 2
Solution
A)
Problem 1. Max sold 30 burgers during half-time. That is 8 more than twice the number Zack sold. How
many did Zack sell?
(4 points)
 2x − 8 = 30  2 (x + 8) = 30  2x + 8 = 30  Add 8 to both sides of the equation.
 Distribute 2 to each term inside of the parentheses.  Divide both sides of the equation by 2.
 Subtract 8 on both sides of the equation.  Subtract 16 from both sides of the equation.  x = 7  x = 11  x = 19

Answer 1

Let x = number of burgers Zack sold.

Equation: 2x + 8 = 30 (“8 more than twice Zack’s amount” equals 30)

Step 1: Subtract 8 from both sides → 2x = 22
Step 2: Divide both sides by 2 → x = 11

Solution: Zack sold 11 burgers.

(From your listed items the correct ones are: 2x + 8 = 30; Subtract 8 on both sides; Divide both sides of the equation by 2; x = 11.)
