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).

[Q]: Suppose 0 = 5*a + 3*q - 104, 0 = 5*a - 0*q - 3*q - 116. Suppose 0 = -b - 3*b + 5*n + 88, b - 3*n - a = 0. Suppose b = -0*f + 2*f. What is the tens digit of f?
[A]: 1


[Q]: Let b be 4 + -1 + 72490/16. Let r = 4524 - b. Find the common denominator of 4 + -2 - (-83)/(-4) and r.
[A]: 8


[Q]: Suppose 5*d + 2*m - 50 = 0, d + 4*m - 8 - 2 = 0. Let w(x) = -x**2 + 11*x - 9. Let r be w(d). Calculate the remainder when 17 is divided by (-33)/(-3) - 2/r.
[A]:
