[tex] \frac{5z}{3x} - \frac{2x}{5y} - \frac{y}{4z} = [/tex] jawab dg cara

[tex] \frac{5z}{3x} - \frac{2x}{5y} - \frac{y}{4z} \\ = \frac{5y \times 5z - 3x \times 2x}{15xy} - \frac{y}{4z} \\ = \frac{25yz - 6x ^{2} }{15xy} - \frac{y}{4z} \\ = \frac{4z(25yz - 6x ^{2}) - 15xy(y) }{60xyz} \\ = \frac{100yz ^{2} - 24x ^{2}z - 15xy ^{2} }{60xyz} [/tex]

Maaf Kalau Salah
