30.3x-4+33.92x=-68.22
Me tāpiri te 33.92x ki ngā taha e rua.
64.22x-4=-68.22
Pahekotia te 30.3x me 33.92x, ka 64.22x.
64.22x=-68.22+4
Me tāpiri te 4 ki ngā taha e rua.
64.22x=-64.22
Tāpirihia te -68.22 ki te 4, ka -64.22.
x=\frac{-64.22}{64.22}
Whakawehea ngā taha e rua ki te 64.22.
x=-1
Whakawehea te -64.22 ki te 64.22, kia riro ko -1.
