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).

Question: Let y(m) = m**2 - m + 1. Let i be y(2). Suppose -9 = 2*n + 3*j, -i*n + 3*j = -4 - 5. Suppose -d + 4 = b, -2 = 4*d - 5*b - n. What is the units digit of d?

Answer: 2


Question: Let q = 10 - -75. Suppose 2*s = 2*t + 30, 5*s - q = s - t. Suppose -4*i + 4 + 5 = -a, 4*a - i = 24. Solve -s = -2*g + a*g for g.

Answer: -4


Question: Let p be (-1 + -3)*2/(-4). Let j(o) = -o**3 + 3*o**2 - 3*o. Let x be j(p). Let a(t) = -2*t**3 - 2*t**2 + t. Let z be a(x). Solve -18 + z = -3*c for c.
