1x-0x=140-x+0\times 125x
Whakareatia te 0 ki te 125, ka 0.
1x-0=140-x+0\times 125x
Ko te tau i whakarea ki te kore ka hua ko te kore.
1x-0=140-x+0x
Whakareatia te 0 ki te 125, ka 0.
1x-0=140-x+0
Ko te tau i whakarea ki te kore ka hua ko te kore.
1x-0=140-x
Tāpirihia te 140 ki te 0, ka 140.
1x-0+x=140
Me tāpiri te x ki ngā taha e rua.
x+x=140
Whakaraupapatia anō ngā kīanga tau.
2x=140
Pahekotia te x me x, ka 2x.
x=\frac{140}{2}
Whakawehea ngā taha e rua ki te 2.
x=70
Whakawehea te 140 ki te 2, kia riro ko 70.
