10x-16=24+12+133-15
Pahekotia te 3x me 7x, ka 10x.
10x-16=36+133-15
Tāpirihia te 24 ki te 12, ka 36.
10x-16=169-15
Tāpirihia te 36 ki te 133, ka 169.
10x-16=154
Tangohia te 15 i te 169, ka 154.
10x=154+16
Me tāpiri te 16 ki ngā taha e rua.
10x=170
Tāpirihia te 154 ki te 16, ka 170.
x=\frac{170}{10}
Whakawehea ngā taha e rua ki te 10.
x=17
Whakawehea te 170 ki te 10, kia riro ko 17.
