128x - 32 - 3x - 54 + x + 2 = 0
128x - 3x + x + 2 - 32 - 54 = 0
126x - 84 = 0
126x = 84
x = 2/3
1/12, as 3 times 4 equals 12, and it contains 4 letters.
4 sets Step-by-step explanation: The greatest common factor (GCF) of 16 and 12 is 4, which is the largest number that divides both evenly. This can be concluded from examining the factors: 12 = 4·3 and 16 = 4·4, or by confirming that the difference of the two numbers (4) can divide both without remainder. Hence, the maximum number of identical sets Mandy can create is 4. Each of these 4 sets will consist of 4 sheets of paper and 3 envelopes.
