19. x = 6, y = 3, t = 11

20. x = −1, y = 0, t = 11

21. a = 8, b = 9, c = 7

22. x = 21

23. a = 0, b = 0, f = 3, g = −5

24. t = 3, w = 4, y = 11, u = 13, v = 16

25.

\begin{matrix} t = 9, \\ x + 5 = 24 \to x = 19 \\ y - 3 = 7 \to y = 10 \end{matrix}

26.

\begin{matrix} k = 11 \\ p - 4 = 15 \to p = 19 \\ q + 8 = 28 \to q = 20 \end{matrix}

27.

\begin{matrix} t - 3 = 6 + 11 \to t = 20 \\ m + 12 - 4 = 16 \to m = 8 \\ n + 3 + 8 = 2 n \to n = 11 \end{matrix}

28.

\begin{matrix} - 6 + p = 11 \to p = 17 \\ 4 + q = \end{matrix}
