TASK DEFINITION: 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).
PROBLEM: Suppose -4*s - 3 = -47. What is the least common multiple of 21 and s?

SOLUTION: 231

PROBLEM: Four letters picked without replacement from {w: 2, k: 1, o: 1, a: 2, b: 2}. What is prob of picking 1 k, 2 a, and 1 b?

SOLUTION: 1/35

PROBLEM: Let x(h) = -h**3 + 8*h**2 + 2*h - 12. Let v be 5/15 + (-46)/(-6). Let j be x(v). Solve 0 = 5*w + 4*b, -4*w = -b + 5*b - j for w.

SOLUTION:
-4
