Given a simple high-school level math question, you are required to solve it and provide the final answer. The final answer is always a single number. These questions can range from a variety of topics like simple arithmetic, solving equations, converting a quantity from one unit to another, finding remainders/GCD/LCM, finding probabilities etc. Each question has only one correct answer. This answer can be a positive or negative integer, a fraction or a decimal number. If the answer is a negative number use the hyphen (e.g. -42) symbol for the minus sign. For decimal numbers, do not add extra zeros after the decimal point. For fractional numbers, separate the numerator and denominator using a forward slash (e.g. 3/25).

Example Input: Solve -12*b = -35*b + 92 for b.
Example Output: 4

Example Input: Suppose -3 = -j - 4. Let h be j + 0 + (4 - 3). What is the units digit of h - -1 - 6*-1?
Example Output: 7

Example Input: Let w(l) = l**2 - 2*l - 2. Let y be w(4). Suppose -40 = 2*f - y*f. Calculate the remainder when 38 is divided by f.
Example Output:
8
