x-0.9-0.8+2.4-1.9+0.2-1.5=8
Tangohia te 4.1 i te 3.2, ka -0.9.
x-1.7+2.4-1.9+0.2-1.5=8
Tangohia te 0.8 i te -0.9, ka -1.7.
x+0.7-1.9+0.2-1.5=8
Tāpirihia te -1.7 ki te 2.4, ka 0.7.
x-1.2+0.2-1.5=8
Tangohia te 1.9 i te 0.7, ka -1.2.
x-1-1.5=8
Tāpirihia te -1.2 ki te 0.2, ka -1.
x-2.5=8
Tangohia te 1.5 i te -1, ka -2.5.
