ALGEBRA PUZZLES

 

A varialble is a letter (X, Y, H, or T, etc.) that stands for a number or a range of numbers.

 

Look at these examples and try to figure out what number the variable stands for.  (Hint:  The variable will be the same number if it shows up more than once in the problem.)

 

Examples:

1.  T + T = 64            Solution:  8 x 8 = 64, so T = 8

2.  H + H = 24           Solution:  12 + 12 = 24, so H = 12

3.  Y + 2 = 19            Solution:  17 + 2 = 19, so Y = 17

 

Now you try some:

 

1. L + L = 8 , so L = ________

2.  H x H = 16, so H = ________

3.  T + 1 = 16, so T = ________

4.  C + C = 10, so C = ________

5.  K - 1 = 13, so K = ________

6.  5 + Y = 6, so Y = ________

7.  M x M = 81, so M = ________

8.  L - 7 = 9, so L = ________

9.  11 + X = 16, so X = ________

10. E x 8 = 8, so E = ________
