instruction:
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:
Suppose v + 5 = 10. Suppose -4*b = 4*d - 3*d - 23, -3*b = -v*d. Let h(q) = -q - 1. Let j be h(-4). Solve j = -2*t - d for t.
answer:
-3


question:
Let c(t) = t + 12. Let z be c(-10). Solve -8 - z = 5*g for g.
answer:
-2
