Kua tāruatia ki te papatopenga
7\pi x-15-2x=12
Tangohia te 2x mai i ngā taha e rua.
7\pi x-2x=12+15
Me tāpiri te 15 ki ngā taha e rua.
7\pi x-2x=27
Tāpirihia te 12 ki te 15, ka 27.
\left(7\pi -2\right)x=27
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(7\pi -2\right)x}{7\pi -2}=\frac{27}{7\pi -2}
Whakawehea ngā taha e rua ki te 7\pi -2.
x=\frac{27}{7\pi -2}
Mā te whakawehe ki te 7\pi -2 ka wetekia te whakareanga ki te 7\pi -2.
