Algebra Code Breaker Puzzles

Evaluate each expression using the given values, or solve each equation. Use the code table in that section to turn each numerical answer into a letter. Write the letters in order to uncover each code word.

Expression Detective

For every expression in this section, use x = 4 and y = 3. Code table: 5 = R, 7 = C, 9 = H, 10 = P, 11 = I, 12 = E.

1.Evaluate x + 3. Write the value and its matching code letter.
2.Evaluate 2x + y. Write the value and its matching code letter.
3.Evaluate x + y + 3. Write the value and its matching code letter.
4.Evaluate 3x − y. Write the value and its matching code letter.
5.Evaluate 2x + 4. Write the value and its matching code letter.
6.Evaluate x + y − 2. Write the value and its matching code letter.
7.Write the six code letters from the Expression Detective questions in order to reveal the code word.

Equation Solver

Solve each equation, then use this code table to translate your answer: 2 = S, 3 = O, 5 = L, 7 = V, 9 = E, 11 = R, 21 = V.

8.Solve n + 5 = 7. Write the value of n and its matching code letter.
9.Solve m − 4 = −1. Write the value of m and its matching code letter.
10.Solve 2k = 10. Write the value of k and its matching code letter.
11.Solve p ÷ 3 = 7. Write the value of p and its matching code letter.
12.Solve 3t = 27. Write the value of t and its matching code letter.
13.Solve w − 6 = 5. Write the value of w and its matching code letter.
14.Write the six code letters from the Equation Solver questions in order to reveal the code word.
