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).

[EX Q]: Suppose -3*x = -2*y, -y - 3*x = -6*x. Let c = 2 - y. Suppose -c*u = 5*t - 1 + 9, 0 = 4*u + 3*t + 2. What is the remainder when 2 is divided by u?
[EX A]: 0

[EX Q]: What is 3/8 of a milligram in micrograms?
[EX A]: 375

[EX Q]: Suppose 56 = -2*w - 5*r, r - 5*r + 38 = -3*w. Let y = w - -20. Solve -3*u = 4*g - 5*u - y, -6 = -2*u for g.
