This is why they are proving to be so difficult to solve - they were chosen precisely for that reason. However, this does not mean they cannot be solved. Fermat's Last Theorem is an example of the same type of problem - first proposed by French mathematician Pierre de Fermat in the margin of a textbook in 1637, it took 358 years for a. Start by solving the division part of the equation. In order to do that, in case you forgot, you have to flip the fraction and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 - 9 + 1, and from there you can simply work from left to right and get your final answer: 1. 11 There are two correct ways to solve it. The first way to find the solution is to add the equation, then combine the sum with that of the previous equation. The second solution involves multiplying the second number of the equation by the number you are adding to it. The correct answer could either be 40 or 96
