Kua tāruatia ki te papatopenga
8x-\pi =-2\sqrt{2}
Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 4,2.
8x=-2\sqrt{2}+\pi
Me tāpiri te \pi ki ngā taha e rua.
8x=\pi -2\sqrt{2}
He hanga arowhānui tō te whārite.
\frac{8x}{8}=\frac{\pi -2\sqrt{2}}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{\pi -2\sqrt{2}}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
x=\frac{\pi }{8}-\frac{\sqrt{2}}{4}
Whakawehe -2\sqrt{2}+\pi ki te 8.
