Solve: \( \frac{3}{4} y-8=4-\frac{1}{4} y \) \( y=3 \) \( y=-4 \) \( y=24 \) \( y=12 \)

Exercice 9 Déterminer les nombres manquants: \[ \text { a) }(-1) \times(-2) \times \ldots \ldots(-3)=60 \]

Find the value of \( k \) \( \left|\begin{array}{ccc}2 & -2 & 1 \\ k & 1 & 0 \\ 3 & 1 & 2\end{array}\right| k= \)

\( 17x-5=5(2x+1). \)

b) \( \left\{\begin{array}{c}x+y=5 \\ x-2 y=2\end{array}\right. \)

Tukarkan persamaan garis lurus \( x-2 y=4 \) kepada bentuk \( \frac{x}{a}+\frac{y}{b}=1 \) Convert a straight line equation \( x-2 y=4 \) to the form \( \frac{x}{a}+\frac{y}{b}=1 \) \( \begin{array}{ll}\text { A. } \frac{x}{2}+\frac{y}{4}=1 & \text { C. } \frac{x}{2}+\frac{y}{(-4)}= \\ \text { B. } \frac{x}{4}+\frac{y}{2}=1 & \text { D. } \frac{x}{4}+\frac{y}{(-2)}=\end{array} \)
