Equation
Step 1
Step 2
Solution
B) Problem 2. Kelly wore 25 bracelets last week. That is 5 less than three times the number Jessie wore
this week. How many did Jessie wear this week? (4 points)
 3x − 5 = 25  3 (x − 5) = 25  3x + 5 = 25  3 (x + 5) = 25  Add 5 to both sides of the equation.
 Subtract 5 from both sides of the equation.  Distribute 3 to each term inside of the parentheses.
 Divide both sides of the equation by 3.  x = 13

Answer 1

Equation: 3x − 5 = 25

Step 1: Add 5 to both sides → 3x = 30

Step 2: Divide both sides by 3 → x = 10

Check: 3(10) − 5 = 30 − 5 = 25, which matches Kelly’s 25 bracelets.

Note: x = 10 is the correct solution; none of the provided solution choices (13 1/3, 3 1/3, 6 2/3, 1) are correct.
