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).

Let b(x) = 4*x - 5. Let l(s) = 1. Let r(z) = b(z) + 6*l(z). Let n be r(1). Suppose 0 = -3*i + 2*w + 22, 2*w - 36 = -n*i + 5*w. Solve 0 = 2*f + i - 4 for f.
