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:
Solve 0 = 3*v - 3*m - 8 + 5, -5*v - 2*m = -19 for v.
answer:
3


question:

answer:
0


question:
Let p be -2*(-4 - (-5)/2). Suppose 2*b - 4*y - p = -5*y, 2*b - 7 = 3*y. Let n be (3/(-2))/(6/(-32)). Solve 0*v + n = -b*v for v.
answer:

-4
