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).

Input: Consider Input: Let x be (36/(-20))/((-3)/15). Let r(z) = z**2 - 8*z - 5. Let h be r(x). Solve -k + w + 0 - 2 = 0, -h*k - 2*w + 22 = 0 for k.

Output: 3


Input: Consider Input: Suppose -u = -7 + 1. What is the remainder when 17 is divided by u?
