Logic Equations 5x5 - #10 - Brainzilla

How to play

The variables represents unique integers ranging from 1 to the number of variables;
Multiplication is implicit: AB means A times B, or A * B;
Based on the clues (equations and inequations), use the grid to create relations between variables and values:

Click once on a square to mark that value as false;
Click twice to assign the chosen value to the variable;
Click three times to clear the square.

The color of a clue changes after you assign values to all of its variables:

GREEN means that the statement is true;
RED means that the statement is false.

Click on a clue to mark it as used;
The game ends when all values are correctly assigned to the variables.

Tips

Figuring out which variables can't have the lowest or the highest values is a good starting point, e.g, A > B shows that A ≠ 1;
Analyzing the hypothetical equation C + D = 4, we can make the following statements:

C = 1 and D = 3 OR C = 3 and D = 1;
No other variable can be 1 or 3 (see Naked Pairs in our Sudoku Guide).

Another quick tip: A = 2B means that A is even;
Don't be afraid of using pen and paper. Some puzzles might require it.
