Whakaoti mō y
y=\frac{4x}{5}-\frac{14}{5x}
x\neq 0
Whakaoti mō x
x=\frac{\sqrt{25y^{2}+224}+5y}{8}
x=\frac{-\sqrt{25y^{2}+224}+5y}{8}
Graph
Tohaina
Kua tāruatia ki te papatopenga
-5xy-14=-4x^{2}
Tangohia te 4x^{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-5xy=-4x^{2}+14
Me tāpiri te 14 ki ngā taha e rua.
\left(-5x\right)y=14-4x^{2}
He hanga arowhānui tō te whārite.
\frac{\left(-5x\right)y}{-5x}=\frac{14-4x^{2}}{-5x}
Whakawehea ngā taha e rua ki te -5x.
y=\frac{14-4x^{2}}{-5x}
Mā te whakawehe ki te -5x ka wetekia te whakareanga ki te -5x.
y=\frac{4x}{5}-\frac{14}{5x}
Whakawehe -4x^{2}+14 ki te -5x.
