14+38x-114=82
Whakamahia te āhuatanga tohatoha hei whakarea te 38 ki te x-3.
-100+38x=82
Tangohia te 114 i te 14, ka -100.
38x=82+100
Me tāpiri te 100 ki ngā taha e rua.
38x=182
Tāpirihia te 82 ki te 100, ka 182.
x=\frac{182}{38}
Whakawehea ngā taha e rua ki te 38.
x=\frac{91}{19}
Whakahekea te hautanga \frac{182}{38} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
