\( A = \left( \begin{array} { l } { 3 x + 2 y - z = 5 } \\ { 2 x - 3 y + 2 z = 70 } \\ { x + 4 y - 3 z = 8 } \end{array} \right. \)

5.7 Determine the equation of \( h \) if \( h(x)=g(x+1)-2 \)

Roger was told to think of a number, add 20 , then divide the result by 3 . The answer was Jower than Roger's original number. Deteruine the range of possible numbers Roger may have originally chosen.

Diketahui sistem persamaan tinier berikut ini : \[ \begin{array}{l}-1 x+y+2 z=2 \\ 3 x-1 y+z=6 \\ -1 x+3 y+4 z=4\end{array} \] Tentukan solusi persamaan linear tersebut menggunakan metode gauss!

tinh \( a x^{2}+2 x+3 y=6 \)
