![]()
Jawaban:
[tex] \frac{1}{2} p + \frac{3}{4} q = - 6 \: ( \times 1) \\ p - \frac{3}{2} q = 6 \: ( \times \frac{1}{2} ) \\ - - - - - - - - - - - - - - - - \\ \frac{1}{2} p + \frac{3}{4} q = - 6 \\ \frac{1}{2} p - \frac{3}{4}q = 3 \\ - - - - - - - - - - - - - - - - \\ \frac{6}{4} q = - 9 \\ q = - 9 \times \frac{4}{6} = \frac{ - 36}{6} = - 6 \\ \\ p - \frac{3}{2} q = 6 \\ p = 6 + \frac{3}{2} ( - 6) \\ p = 6 - 9 = - 3[/tex]
