To find the values of variables \( a, b, c, \dots, t \), we need to solve the system of equations provided:

\[
\begin{aligned}
1) & \quad a - b - c + \frac{d}{e} = -24 \\
2) & \quad f - \frac{20}{j - k - l} = -30 \\
3) & \quad g - 15 \times m - \frac{8}{24} = -174 \\
4) & \quad h \times n + \frac{0}{2} - p = -15 \\
5) & \quad i + q + r - s \times t = -203 \\
6) & \quad a - f - g + h + i = 12 \\
7) & \quad b \times 20 - 15 + n + q = 202 \\
8) & \quad c - j + m - o + r = 37 \\
9) & \quad d - \frac{k}{8} \times \frac{1}{2} \times s = 10 \\
10) & \quad e + l \times 24 + p + t = 486 \\

Given that there are 20 variables and 10 equations, this system is underdetermined, meaning that there may be multiple solutions or a parameterized solution set. I will attempt to find a solution by solving these equations systematically. Let's go step by step.

### Simplification and Rearrangement:
1) The first equation simplifies directly to:
\[
a - b - c + \frac{d}{e} = -24
\]
2) The second equation can be rearranged as:
\[
f = -30 + \frac{20}{j - k - l}
\]
3) The third equation simplifies to:
\[
g - 15m - \frac{1}{3} = -174 \implies g - 15m = -174 + \frac{1}{3}
\]
4) The fourth equation is:
\[
h \times n - p = -15
\]
5) The fifth equation is:
\[
i + q + r - s \times t = -203
\]
6) The sixth equation is:
\[
a - f - g + h + i = 12
\]
7) The seventh equation is:
\[
20b - 15 + n + q = 202 \implies 20b + n + q = 217
\]
8) The eighth equation is:
\[
c - j + m - o + r = 37
\]
9) The ninth equation simplifies to:
\[
d - \frac{k}{16} \times s = 10
\]
10) The tenth equation is:
\[
e + 24l + p + t = 486
\]
