x 3 16 + x + x 3 7 − 4 x = x 3 16 + x + 7 − 4 x = x 3 23 − 3 x ====================================== t − 1 5 + t 3 = t ( t − 1 ) 5 t + t ( t − 1 ) 3 ( t − 1 ) = t 2 − t 5 t + 3 t − 3 = t 2 − t 8 t − 3
x 3 16 + x + x 3 7 − 4 x 16 + x + 7 − 4 x = 23 − 3 x x 3 23 − 3 x
\[ \frac{5}{t-1} +\frac{3}{t}
\\ \\ \frac{5t+(t-1)(3)}{(t-1)(t)}
\\ \\ \frac{5t+3t-3}{ t^{2}-t }
\\ \\ \frac{8t-3}{ t^{2}-t } \]
To simplify the first question, x 3 16 + x + x 3 7 − 4 x becomes x 3 23 − 3 x . The second question, t − 1 5 + t 3 , simplifies to t ( t − 1 ) 8 t − 3 . Both results have been combined correctly using common denominators.

Jawaban yang benar:Pendapatan = Rp 200.000.000HPP (Harga Pokok Penjualan) = Rp 150.000.000Gross Profit = Pendapatan − HPP= Rp 200.000.000 − Rp 150.000.000= Rp 50.000.000Jadi, gross profit bukan Rp 100.000.000, melainkan Rp 50.000.000.
