x-144=2x+144
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 6,3.
x-144-2x=144
Tangohia te 2x mai i ngā taha e rua.
-x-144=144
Pahekotia te x me -2x, ka -x.
-x=144+144
Me tāpiri te 144 ki ngā taha e rua.
-x=288
Tāpirihia te 144 ki te 144, ka 288.
x=-288
Me whakarea ngā taha e rua ki te -1.
