Graph
Tohaina
Kua tāruatia ki te papatopenga
2x-10=1
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
2x=1+10
Me tāpiri te 10 ki ngā taha e rua.
2x=11
Tāpirihia te 1 ki te 10, ka 11.
x=\frac{11}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{11}{2} y=10
Kua oti te pūnaha te whakatau.
