8. Ahamed says, "I think of a number, subtract 10 and then divide it by 3 . My answer is 26 ". a. Write an equation to show Ahamed's calculation. Use \( x \) for the number he thinks of.

System B \( x-4 y=4 \) \( -x-4 y=4 \)

is the slope of \( 2 x-4 y=8 \)

\begin{tabular}{l|l} System A \\ \( \begin{aligned} x-2 y=6 \\ -x+2 y=6\end{aligned} \) & \( \begin{array}{l}\text { The system has no solution. } \\ \text { The system has a unique solution: } \\ \text { The system has infinitely many solutions. } \\ \text { They must satisfy the following equation: }\end{array} \)\end{tabular}

ii. \( \quad \log _{3} x-4 \log _{x} 3=0 \)

Fungsi kuadratik di bawah melalui titik sepert yang berikut. (a) \( f(x)=x^{2}+7 x+c \), melalui titik \( (0,5) \)
