Whakaoti mō y
y=\frac{81-9x^{2}}{10}
Whakaoti mō x (complex solution)
x=-\sqrt{-\frac{10y}{9}+9}
x=\sqrt{-\frac{10y}{9}+9}
Whakaoti mō x
x=\frac{\sqrt{81-10y}}{3}
x=-\frac{\sqrt{81-10y}}{3}\text{, }y\leq \frac{81}{10}

Kua tāruatia ki te papatopenga
y=\left(-0.9x-2.7\right)\left(x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -0.9 ki te x+3.
y=-0.9x^{2}+8.1
Whakamahia te āhuatanga tuaritanga hei whakarea te -0.9x-2.7 ki te x-3 ka whakakotahi i ngā kupu rite.
