Kua tāruatia ki te papatopenga
\pi x+3+9x=0
Me tāpiri te 9x ki ngā taha e rua.
\pi x+9x=-3
Tangohia te 3 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\left(\pi +9\right)x=-3
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(\pi +9\right)x}{\pi +9}=-\frac{3}{\pi +9}
Whakawehea ngā taha e rua ki te \pi +9.
x=-\frac{3}{\pi +9}
Mā te whakawehe ki te \pi +9 ka wetekia te whakareanga ki te \pi +9.
